Image Search


Ongoing draft
Sung-eui Yoon, Copyright 2021


This is an on-going book that I'm writing. This covers basic concepts of image search and related topics such as descriptors, indexing schemes, and matching techniques. t will also cover many advanced techniques including some of recent techniques.
Why am I writing this book?
  • Search is one of fundamental tools for identifying and retrieving relevant information. Since images and videos are getting more widely used thanks to various devices advances (e.g., mobile phones and camera), there have been growing demands for image search. Even though it has been heavily studied, various topics related to image search have not been coherently treated yet.
  • Albeit the importance of image search, there have been only few books that cover topics related to the image search. Also, those books are rather expensive and did not cover recent topics. I'll thus make my book totally free and easily accessible at the web. I will also discuss recent topics. Once materials of my book are mature, I'll try to publish my book at some publisher. Nonetheless, the book will be available freely on the web, as one of my prior books Rendering by Sung-eui Yoon
