Social media platforms can utilize image captioning to improve accessibility and enable better content discovery

Image captioning Review

Users have praised image captioning for its ability to generate accurate and descriptive captions for a wide range of images. They appreciate its potential for enhancing accessibility and improving image search capabilities. However, some users have noted that image captioning models can sometimes generate captions that are generic or lack specific details about the image. There is also room for improvement in handling complex scenes and understanding the broader context of an image.

Who is suitable to use Image captioning?

A visually impaired user can use an image captioning app to understand the content of images shared on social media

A user searching for specific images (e.g., 'a dog playing with a ball') can find relevant results thanks to automatically generated captions

How does Image captioning work?

To implement image captioning, you typically need a pre-trained image captioning model (e.g., based on encoder-decoder architecture) and a dataset of images and their corresponding captions. The steps involve: (1) Preprocessing the input image, (2) Extracting visual features using a convolutional neural network (CNN), (3) Feeding the visual features into a language model (e.g., LSTM) to generate the caption, and (4) Postprocessing the generated caption (e.g., removing redundant words). Popular deep learning frameworks such as TensorFlow and PyTorch provide pre-trained image captioning models that can be fine-tuned on custom datasets.

Advantages of Image captioning
