In this chapter, we will deal with the problem of captioning images. This involves detecting the objects and also coming up with a text caption for the image. Image captioning also can be called Image to Text translation. Once thought a very tough problem, we have reasonably good results on this now. For this chapter, a dataset of images with corresponding captions is required. In this chapter, we will discuss the techniques and applications of image captioning in detail.
We will cover the following topics in this chapter:
- Understand the different datasets and metrics used to evaluate them
- Understand some techniques used for natural language processing problems
- Different words for vector models
- Several algorithms for image captioning
- Adverse results and scope for improvement
