This program is used to find point matches between two images. The procedure can be divided into two parts:
1) Firstly, using SIFT matching algorithm to find sparse point matches between two images.
2) Secondly, using "quasi-dense propagation" algorithm to get "quasi-dense" point matches. "Quasi-dense" means the matches are distributed evenly, and have quantities been improved significantly.
