Image matching is a critical process for various image applications such as identifying same features from multiple looking images, change detection, feature tracking, and image alignment. ...
A matching task typically has two steps, i.e., extraction of distinct points (or features) from one image, and the search for the counterpart in the corresponding image. ...
Scale Invariant Feature Transform (SIFT) matching is designed to extract invariant features from images and to perform matching. ...
