Chapter 5. Similarity-based Image Retrieval

A big part of the data that we work with is presented as an image, drawing, or photo. In this chapter, we will implement a similarity-based image retrieval without the use of any metadata or concept-based image indexing. We will work with distance metric and dynamic warping to retrieve the most similar images.

In this chapter we will cover:

Image similarity search
Dynamic time warping
Processing the image dataset
Implementing DTW
Analyzing the results
