Abstract

This paper proposes a new and more reliable method for template matching that builds the algorithm that automatically divides blocks into conventional method. A template image is divided with arbitrary block size. In each block, to calculate the degree of similarity among contiguous block. If the degree of similarity is high, their blocks are connected. In addition, to calculate the degree of similarity uses correlation coefficient from ZNCC. Template matching is performed using foregoing blocks by EBM. The experimental results show that the proposed method was robust to images partially concealed and images uniformly changed gray level with the conventional methods.
