Abstract: In order to solve image mosaic optimization problems, a novel improved algorithm is proposed based on the traditional Harris vertex examination algorithm. The proposed algorithm effectively avoids the affecting of selecting kin the corner response function and the threshold T in detection process. During the process of image mosaic,image regis- tration was improved by NCC. And the mean method was used to fuse spliced images and eliminate stitching gaps. In or- der to verify the effectiveness, the proposed algorithm was evaluated in an example of image mosaic. Simulation results show that this algorithm increases the precision and the efficiency of image mosaic. Consectucntly, this algorithm can ef- ficicntly achieve a goal of seamless mosaic and satisfy the actual demand.
