算法

The main calculation in the particle image matching algorithm is to have the two visual seriate images taken the cross-correlation arithmetic based on the fast fourier transform. This paper discusses the basic principle of the cross-correlation arithmetic in detail, discuss each stage of its produce and development and also discuss the thinking, the merit and the defect of each algorithm. On the base of all these discussing, we confirm our algorithm and realize it in programming with C++.
