Abstract

The paper proposes a new methods which used in image matching Harris corner extraction and corner matching. On the basis of the original Harris algorithm, the efficiency of extracting corners is improved by reducing the number of computing the corner response value. Then the NCC algorithm is used to match the extracted corners, and the matching accuracy is improved by choosing the threshold (auto correlation coefficient). The experimental results show that the proposed algorithm reduces the time of corner extraction, and is superior to the traditional Harris corner extraction method. Moreover, when matching the two images with NCC matching algorithm, the mismatching is reduced. Finally, the Ransac algorithm is used to remove the false matches.
