The image match technology has become one of domain key technologies in pictorial information processing, and it has the widespread application background. Existed image match algorithm may divide into two kinds: one is based on image geometry characteristic match and another is based on picture element grey level match. It is mainly used correlation method of correlates to realize the template match algorithm which is based on the pixel grey level. And the key is how to reduce the computation load. The main idea of this algorithm is to find the parts of close region by gradation projecting in those searched regions first. Then makes the correlation computation in these regions in order to discover the most superior match region.
