Italics are used very often, while the font size of image captions is usually smaller than the body copy. II. Automatic image annotation (also known as automatic image tagging or linguistic indexing) is the process by which a computer system automatically assigns metadata in the form of captioning or keywords to a digital image.This application of computer vision techniques is used in image retrieval systems to organize and locate images of interest from a database. The task of image captioning can be divided into two modules logically - one is an image based model - which extracts the features and nuances out of our image, and the other is a language based model - which translates the features and objects given by our image based model to a natural sentence.. For our image based model (viz encoder) - we usually rely .
