Neural network models have come to dominate the field of automatic caption generation this is primarily because the methods are demonstrating state-of-the-art results. In this post, we will focus our attention on describing images, which we will describe as ‘ image captioning.’ Neural Captioning Model The general problem can also be extended to describe images over time in video. Taken from “Deep Visual-Semantic Alignments for Generating Image Descriptions”, 2015. Classify ImageĪssign an image a class label from one of hundreds or thousands of known classes.Įxample of annotation regions of an image with descriptions. Show and Tell: A Neural Image Caption Generator, 2015.įurther, the problems can range in difficulty let’s look at three different variations on the problem with examples. It combines both computer vision and natural language processing and marks a true challenging problem in broader artificial intelligence.Īutomatically describing the content of an image is a fundamental problem in artificial intelligence that connects computer vision and natural language processing. Deep Visual-Semantic Alignments for Generating Image Descriptions, 2015.Ī solution requires both that the content of the image be understood and translated to meaning in the terms of words, and that the words must string together to be comprehensible. However, this remarkable ability has proven to be an elusive task for our visual recognition models It is an easy problem for a human, but very challenging for a machine.Ī quick glance at an image is sufficient for a human to point out and describe an immense amount of details about the visual scene. The problem is sometimes called “ automatic image annotation” or “ image tagging.” This post is divided into 3 parts they are:ĭescribing an image is the problem of generating a human-readable textual description of an image, such as a photograph of an object or scene. Kick-start your project with my new book Deep Learning for Natural Language Processing, including step-by-step tutorials and the Python source code files for all examples. How the elements of the model can be arranged into an Encoder-Decoder, possibly with the use of an attention mechanism.About the elements that comprise a neural feature captioning model, namely the feature extractor and language model. ![]()
