What are the feature-based image matching algorithms?

Methods based on local constraints: There are area matching (mainly based on windows), feature matching (based on feature points, such as SIFT), and phase matching (mainly using filtering).

Methods based on global constraints: mainly include dynamic programming algorithms, graph cut algorithms, artificial intelligence algorithms, collaborative algorithms, confidence propagation algorithms, nonlinear diffusion algorithms, etc.

You can find out the development history by reading two books on photogrammetry or reading a few papers
