I hope this gives you an idea of how we are approaching this problem statement. Image-Caption-Generator - A simple implementation of neural image caption generator #opensource. There has been immense research in the attention mechanism and achieving a state of the art results. Given an image like the example below, our goal is to generate a caption such as "a surfer riding on a wave". Data Link: Flickr image dataset. Official Implementation of our pSp paper for both training and evaluation. We will also limit the vocabulary size to the top 5000 words to save memory. This ability of self-selection is called attention. An email for the linksof the data to be downloaded will be mailed to your id. Generating Captions from the Images Using Pythia Head over to the Pythia GitHub page and click on the image captioning demo link. This implementation will require a strong background in deep learning. Python Image And Audio Captcha Example. It was able to identify the yellow shirt of the woman and her hands in the pocket. Top 14 Artificial Intelligence Startups to watch out for in 2021! These models were among the first neural approaches to image captioning and remain useful benchmarks against newer models. This class generates images by making a request to the Plotly image server. image_model = tf.keras.applications.VGG16(include_top=False, hidden_layer = image_model.layers[-1].output, image_features_extract_model = tf.keras.Model(new_input, hidden_layer), encode_train = sorted(set(img_name_vector)), image_dataset = tf.data.Dataset.from_tensor_slices(encode_train), image_dataset = image_dataset.map(load_image, num_parallel_calls=tf.data.experimental.AUTOTUNE).batch(64), We extract the features and store them in the respective. But this isn’t the case when we talk about computers. They seek to describe the world in human terms. You can see even though our caption is quite different from the real caption, it is still very accurate. By default, we use train2014, val2014, val 2017 for training, validating, and testing, respectively. return tf.compat.v1.keras.layers.CuDNNLSTM(units, '''The encoder output(i.e. Let’s take an example to understand better: Our aim would be to generate a caption like “two white dogs are running on the snow”. The code was written for Python 3.6 or higher, and it has been tested with PyTorch 0.4.1. Then, it would decode this hidden state by using an LSTM and generate a caption. Driver Drowsiness Detection; Image Caption Generator Identify the different objects in the given image. Implement different attention mechanisms like Adaptive Attention with Visual Sentinel and. 625 batches if batch size= 64. Image Caption Generator Web App: A reference application created by the IBM CODAIT team that uses the Image Caption Generator Resources and Contributions If you are interested in contributing to the Model Asset Exchange project or have any queries, please follow the instructions here . Implement attention mechanism to generate caption in python . In this article, multiple images are equivalent to multiple source language sentences in the translation. The code for data generator is as follows: Code to load data in batches 11. Next, we tokenize the captions and build a vocabulary of all the unique words in the data. Let’s define the image feature extraction model using VGG16. The main advantage of local attention is to reduce the cost of the attention mechanism calculation. Specifically, it uses the Image Caption Generator to create a web application that captions images and lets you filter through images-based image content. Here we will be making use of Tensorflow for creating our model and training it. print ('Epoch {} Loss {:.6f}'.format(epoch + 1, print ('Time taken for 1 epoch {} sec\n'.format(time.time() - start)), attention_plot = np.zeros((max_length, attention_features_shape)), hidden = decoder.reset_state(batch_size=1), temp_input = tf.expand_dims(load_image(image)[0], 0), img_tensor_val = image_features_extract_model(temp_input), img_tensor_val = tf.reshape(img_tensor_val, (img_tensor_val.shape[0], -1, img_tensor_val.shape[3]), dec_input = tf.expand_dims([tokenizer.word_index['']], 0), predictions, hidden, attention_weights = decoder(dec_input, features, hidden), attention_plot[i] = tf.reshape(attention_weights, (-1, )).numpy(), predicted_id = tf.argmax(predictions[0]).numpy(), result.append(tokenizer.index_word[predicted_id]). def plot_attention(image, result, attention_plot): temp_att = np.resize(attention_plot[l], (8, 8)), ax = fig.add_subplot(len_result//2, len_result//2, l+1), ax.imshow(temp_att, cmap='gray', alpha=0.6, extent=img.get_extent()), rid = np.random.randint(0, len(img_name_val)), image = '/content/gdrive/My Drive/FLICKR8K/Flicker8k_Dataset/2319175397_3e586cfaf8.jpg', # real_caption = ' '.join([tokenizer.index_word[i] for i in cap_val[rid] if i not in [0]]), # remove and from the real_caption, real_caption = 'Two white dogs are playing in the snow', result_final = result_join.rsplit(' ', 1)[0], score = sentence_bleu(reference, candidate), print ('Prediction Caption:', result_final), plot_attention(image, result, attention_plot), real_caption = ' '.join([tokenizer.index_word[i] for i in cap_val[rid] if i not in [0]]), print(f"time took to Predict: {round(time.time()-start)} sec"). Prerequisites sudo apt update && sudo apt install -y python3-pip lxd After the installation you will need to configure your lxd environment. Create your Own Image Caption Generator using Keras! Image caption generator is a task that involves computer vision and natural language processing concepts to recognize the context of an image and describe them in a natural language like English. Rather than compressing an entire image into a static representation, the Attention mechanism allows for salient features to dynamically come to the forefront as and when needed. We have successfully implemented the Attention Mechanism for generating Image Captions. Attention models can help address this problem by selecting the most relevant elements from an input image. SOURCE CODE: ChatBot Python Project. Things you can implement to improve your model:-. To get started, try to clone the repository. If will also use matplotlib module to display the image in the matplotlib viewer. Local attention first finds an alignment position and then calculates the attention weight in the left and right windows where its position is located and finally weights the context vector. To do this we define a function to limit the dataset to 40000 images and captions. Here's an alternative template that uses py.image.get to generate the images and template them into an HTML and PDF report. we will build a working model of the image caption generator by using CNN (Convolutional Neural Networks) and LSTM (Long short … All hidden states of the encoder and the decoder are used to generate the context vector. We must all preprocess all the images to the same size, i.e, 224×224 before feeding them into the model. Next, let’s visualize a few images and their 5 captions: Next let’s see what our current vocabulary size is:-. Image Source; License: Public Domain. Here we can see our caption defines the image better than one of the real captions. The Dataset of Python based Project. Hence, the preprocessing script saves CNN features of different images into separate files. Requirements; Training parameters and results; Generated Captions on Test Images; Procedure to Train Model; Procedure to Test on new images; Configurations (config.py) Frequently encountered problems; TODO; … Hence we remove the softmax layer from the model. There has been immense. from nltk.translate.bleu_score import sentence_bleu, from keras.preprocessing.sequence import pad_sequences, from keras.layers import Dense, BatchNormalization, from keras.callbacks import ModelCheckpoint, from keras.preprocessing.image import load_img, img_to_array, from keras.preprocessing.text import Tokenizer, from keras.applications.vgg16 import VGG16, preprocess_input, from sklearn.model_selection import train_test_split, image_path = "/content/gdrive/My Drive/FLICKR8K/Flicker8k_Dataset", dir_Flickr_text = "/content/gdrive/My Drive/FLICKR8K/Flickr8k_text/Flickr8k.token.txt", print("Total Images in Dataset = {}".format(len(jpgs))), data = pd.DataFrame(datatxt,columns=["filename","index","caption"]), data = data.reindex(columns =['index','filename','caption']), data = data[data.filename != '2258277193_586949ec62.jpg.1'], uni_filenames = np.unique(data.filename.values), captions = list(data["caption"].loc[data["filename"]==jpgfnm].values), image_load = load_img(filename, target_size=target_size), ax = fig.add_subplot(npic,2,count,xticks=[],yticks=[]), print('Vocabulary Size: %d' % len(set(vocabulary))), text_no_punctuation = text_original.translate(string.punctuation). You can see we were able to generate the same caption as the real caption. The attention mechanism is a complex cognitive ability that human beings possess. Did you find this article helpful? The model predicts a target word based on the context vectors associated with the source position and the previously generated target words. This repository contains PyTorch implementations of Show and Tell: A Neural Image Caption Generator and Show, Attend and Tell: Neural Image Caption Generation with Visual Attention. You can read How To Run Python In Eclipse With PyDev to learn more. Now you can see we have 40455 image paths and captions. This is a Data Science project. (adsbygoogle = window.adsbygoogle || []).push({}); A Hands-on Tutorial to Learn Attention Mechanism For Image Caption Generation in Python. This ability of self-selection is called attention. To accomplish this we will see how to implement a specific type of Attention mechanism called Bahdanau’s Attention or Local Attention. [Deprecated] Image Caption Generator. The advantage of a huge dataset is that we can build better models. The web application provides an interactive user interface that is backed by a lightweight Python server using Tornado. 'hidden') and, the decoder input (which is the start token)(i.e. Source Code: Chatbot Project in Python . Deep Learning is a very rampant field right now – with so many applications coming out day by day. In an interview, a resume with projects shows interest and sincerity. Show and Tell: A Neural Image Caption Generator Oriol Vinyals Google vinyals@google.com Alexander Toshev Google toshev@google.com Samy Bengio Google bengio@google.com Dumitru Erhan Google dumitru@google.com Abstract Automatically describing the content of an image is a fundamental problem in artificial intelligence that connects computer vision and natural language processing. Make use of the larger datasets, especially the MS COCO dataset or the Stock3M dataset which is 26 times larger than MS COCO. Generate the mask using np.zeros: mask = np.zeros(img.shape[:2], np.uint8) Draw contours: cv2.drawContours(mask, [i],-1, 255, -1) Apply the bitwise_and operator: new_img = cv2.bitwise_and(img, img, mask=mask) Display the original image: cv2.imshow("Original Image", img) Display the resultant image: cv2.imshow("Image with background … Next, let’s define the encoder-decoder architecture with attention. We create a dataframe to store the image id and captions for ease of use. To train computers so that they can identify what’s there in the image seemed impossible back in the time. First, you need to download images and captions from the COCO website. To accomplish this, you'll use an attention-based model, which enables us to see what parts of the image the model focuses on as it generates a caption. The architecture defined in this article is similar to the one described in the paper “Show and Tell: A Neural Image Caption Generator”:-, We define our RNN based on GPU/CPU capabilities-. Next, we save all the captions and image paths in two lists so that we can load the images at once using the path set. for i, caption in enumerate(data.caption.values): print('Clean Vocabulary Size: %d' % len(set(clean_vocabulary))), PATH = "/content/gdrive/My Drive/FLICKR8K/Flicker8k_Dataset/". While working on the Udacity project `Meme Generator`, that takes in images and captions them with quotes at a random position, I went extra miles to implement a functionality that will wrap the quote’s body if it is longer than the image width. As Global attention focuses on all source side words for all target words, it is computationally very expensive. batch_features = image_features_extract_model(img). What is Image Caption Generator? This was quite an interesting look at the Attention mechanism and how it applies to deep learning applications. How To Have a Career in Data Science (Business Analytics)? This was quite an interesting look at the Attention mechanism and how it applies to deep learning applications. This functionality is not required in the project rubric since the default quotes are short enough to fit the image in one line. https://medium.com/swlh/image-captioning-in-python-with-keras-870f976e0f18 'x') is passed to the decoder.'''. So the main goal here is to put CNN-RNN together to create an automatic image captioning model that takes in an image as input and outputs a sequence of text that describes the image. def __init__(self, embedding_dim, units, vocab_size): super(Rnn_Local_Decoder, self).__init__(), self.embedding = tf.keras.layers.Embedding(vocab_size, embedding_dim). The attention mechanism is a complex cognitive ability that human beings possess. The attention mechanism aligns the input and output sequences, with an alignment score parameterized by a feed-forward network. Checkout the android app made using this image-captioning-model: Cam2Caption and the associated paper. Define our image and caption path and check how many total images are present in the dataset.

The attention mechanism allows the neural network to have the ability to focus on its subset of inputs to select specific features. for caption  in data["caption"].astype(str): all_img_name_vector.append(full_image_path), print(f"len(all_img_name_vector) : {len(all_img_name_vector)}"), print(f"len(all_captions) : {len(all_captions)}"). Let’s define our greedy method of defining captions: Also, we define a function to plot the attention maps for each word generated as we saw in the introduction-, Finally, let’s generate a caption for the image at the start of the article and see what the attention mechanism focuses on and generates-. The majority of the code credit goes to TensorFlow. You can request the data here. Examples Image Credits : Towardsdatascience 8 Thoughts on How to Transition into Data Science from Different Backgrounds, Using Predictive Power Score to Pinpoint Non-linear Correlations. Attention mechanism has been a go-to methodology for practitioners in the Deep Learning community. We make use of a technique called Teacher Forcing, which is the technique where the target word is passed as the next input to the decoder. Now, let’s quickly start the Python based project by defining the image caption generator. Show and Tell: A Neural Image Caption Generator Oriol Vinyals Google vinyals@google.com Alexander Toshev Google toshev@google.com Samy Bengio Google bengio@google.com Dumitru Erhan Google dumitru@google.com Abstract Automatically describing the content of an image is a fundamental problem in artificial intelligence that connects computer vision and natural language processing. if tokenizer.index_word[predicted_id] == '': dec_input = tf.expand_dims([predicted_id], 0), attention_plot = attention_plot[:len(result), :]. This example will create both an image captcha and an audio captcha use python captcha module. 3. Next, let’s define the training step. To overcome this deficiency local attention chooses to focus only on a small subset of the hidden states of the encoder per target word. The attention mechanism is highly utilized in recent years and is just the start to much more state of the art systems. To evaluate our captions in reference to the original caption we make use of an evaluation method called BLEU. A generator function in Python is used exactly for this purpose. We must remember that we do not need to classify the images here, we only need to extract an image vector for our images. The majority of the code credit goes to TensorFlow tutorials. NPY files store all the information required to reconstruct an array on any computer, which includes dtype and shape information. Feel free to share your complete code notebooks as well which will be helpful to our community members. We will take only 40000 of each so that we can select batch size properly i.e. And this dataset is an upgraded version of Flickr 8k used to build more accurate models. In … These 7 Signs Show you have Data Scientist Potential! Things you can implement to improve your model:-. Let’s begin and gain a much deeper understanding of the concepts at hand! Extract the images in Flickr8K_Data and the text data in Flickr8K_Text. To get started with training a model on SQuAD, you might find the following commands helpful: The show-attend-tell model results in a validation loss of 2.761 after the first epoch. The dataset used is flickr8k. Semantic Attention. Although the implementations doesn't support fine-tuning the CNN network, the feature can be added quite easily and probably yields better performance. As Global attention focuses on all source side words for all target words, it is computationally very expensive. The Flickr 30k dataset has over 30,000 images, and each image is labeled with different captions. files and then pass those features through the encoder. To overcome this deficiency local attention chooses to focus only on a small subset of the hidden states of the encoder per target word. And there it is! Flickr 30k Dataset . Explore and run machine learning code with Kaggle Notebooks | Using data from Flicker8k_Dataset You can make use of Google Colab or Kaggle notebooks if you want a GPU to train it. And the best way to get deeper into Deep Learning is to get hands-on with it. It’s like an iterator which resumes the functionality from the point it left the last time it was called. Take up as much projects as you can, and try to do them on your own. Below is the PyDev project source file list. The advantage of BLEU is that the granularity it considers is an n-gram rather than a word, considering longer matching information. This would help you grasp the topics in more depth and assist you in becoming a better Deep Learning practitioner.In this article, we will take a look at an interesting multi modal topic where w… But RNNs tend to be computationally expensive to train and evaluate, so in practice, memory is limited to just a few elements. Table of Contents. In the calculation, the local attention is not to consider all the words on the source language side, but to predict the position of the source language end to be aligned at the current decoding according to a prediction function and then navigate through the context window, considering only the words within the window. You can make use of Google Colab or Kaggle notebooks if you want a GPU to train it. To understand more about Generators, please read here. Exploratory Analysis Using SPSS, Power BI, R Studio, Excel & Orange, 10 Most Popular Data Science Articles on Analytics Vidhya in 2020, Understand the attention mechanism for image caption generation, Implement attention mechanism to generate caption in python. Please consider using other latest alternatives. I hope this gives you an idea of how we are approaching this problem statement. In Bahdanau or Local attention, attention is placed only on a few source positions. Let’s dive into the implementation! With an Attention mechanism, the image is first divided into n parts, and we compute an image representation of each When the RNN is generating a new word, the attention mechanism is focusing on the relevant part of the image, so the decoder only uses specific parts of the image. A Neural Network based generative model for captioning images. When people receive information, they can consciously ignore some of the main information while ignoring other secondary information. It is used to analyze the correlation of n-gram between the translation statement to be evaluated and the reference translation statement. Adjust Image Contrast. There are also other big datasets like Flickr_30K and MSCOCO dataset but it can take weeks just to train the network so we will be using a small Flickr8k dataset. Image Caption Generator “A picture attracts the eye but caption captures the heart.” Soon as we see any picture, our mind can easily depict what’s there in the image. We extract the features and store them in the respective .npy files and then pass those features through the encoder.NPY files store all the information required to reconstruct an array on any computer, which includes dtype and shape information. batch_features = tf.reshape(batch_features, (batch_features.shape[0], -1, batch_features.shape[3])), path_of_feature = p.numpy().decode("utf-8"). In this way, we can see what parts of the image the model focuses on as it generates a caption. Implementing a Transformer based model which should perform much better than an LSTM. Based on the type of objects, you can generate the caption. At the end of this network is a softmax classifier that outputs a vector of class scores but we don’t want to classify an image, instead we want a set of features that represents the spatial content in the image. Next, let’s Map each image name to the function to load the image:-. Word Embeddings. The data directory should have the following structure: Once all the annotations and images are downloaded to, say, DATA_DIR, you can run the following command to map caption words into indices in a dictionary and extract image features from a pretrained VGG19 network: Note that the resulting directory DEST_DIR will be quite large; the features for training and validation images take up 157GB and 77GB already. A neural network to generate captions for an image using CNN and RNN with BEAM Search. Below is the created image file and audio file. self.gru = tf.keras.layers.GRU(self.units, self.fc1 = tf.keras.layers.Dense(self.units), self.batchnormalization = tf.keras.layers.BatchNormalization(axis=-1, momentum=0.99, epsilon=0.001, center=True, scale=True, beta_initializer='zeros', gamma_initializer='ones', moving_mean_initializer='zeros', moving_variance_initializer='ones', beta_regularizer=None, gamma_regularizer=None, beta_constraint=None, gamma_constraint=None), self.fc2 = tf.keras.layers.Dense(vocab_size), self.Uattn = tf.keras.layers.Dense(units), self.Wattn = tf.keras.layers.Dense(units), # features shape ==> (64,49,256) ==> Output from ENCODER, # hidden shape == (batch_size, hidden_size) ==>(64,512), # hidden_with_time_axis shape == (batch_size, 1, hidden_size) ==> (64,1,512), hidden_with_time_axis = tf.expand_dims(hidden, 1), ''' e(ij) = Vattn(T)*tanh(Uattn * h(j) + Wattn * s(t))''', score = self.Vattn(tf.nn.tanh(self.Uattn(features) + self.Wattn(hidden_with_time_axis))), # self.Wattn(hidden_with_time_axis) : (64,1,512), # tf.nn.tanh(self.Uattn(features) + self.Wattn(hidden_with_time_axis)) : (64,49,512), # self.Vattn(tf.nn.tanh(self.Uattn(features) + self.Wattn(hidden_with_time_axis))) : (64,49,1) ==> score, # you get 1 at the last axis because you are applying score to self.Vattn, '''attention_weights(alpha(ij)) = softmax(e(ij))''', attention_weights = tf.nn.softmax(score, axis=1), # Give weights to the different pixels in the image, ''' C(t) = Summation(j=1 to T) (attention_weights * VGG-16 features) ''', context_vector = attention_weights * features, context_vector = tf.reduce_sum(context_vector, axis=1), # Context Vector(64,256) = AttentionWeights(64,49,1) * features(64,49,256), # context_vector shape after sum == (64, 256), # x shape after passing through embedding == (64, 1, 256), # x shape after concatenation == (64, 1,  512), x = tf.concat([tf.expand_dims(context_vector, 1), x], axis=-1), # passing the concatenated vector to the GRU, # shape == (batch_size, max_length, hidden_size), # x shape == (batch_size * max_length, hidden_size), return tf.zeros((batch_size, self.units)), decoder = Rnn_Local_Decoder(embedding_dim, units, vocab_size), loss_object = tf.keras.losses.SparseCategoricalCrossentropy(, mask = tf.math.logical_not(tf.math.equal(real, 0)), # initializing the hidden state for each batch, # because the captions are not related from image to image, hidden = decoder.reset_state(batch_size=target.shape[0]), dec_input = tf.expand_dims([tokenizer.word_index['']] * BATCH_SIZE, 1), # passing the features through the decoder, predictions, hidden, _ = decoder(dec_input, features, hidden), loss += loss_function(target[:, i], predictions), dec_input = tf.expand_dims(target[:, i], 1), total_loss = (loss / int(target.shape[1])), trainable_variables = encoder.trainable_variables + decoder.trainable_variables, gradients = tape.gradient(loss, trainable_variables), optimizer.apply_gradients(zip(gradients, trainable_variables)).
