Abstract

Abstract:

Based on corner detection, a matching strategy featured point-to-multipoint is presented, from which it is proposed a new image stabilization algorithm for image sequences with both translation and large rotation. The algorithm has made a breakthrough to the limitations of both the traditional algorithms' capability of only resolving translation or small rotation(3° to 5° on average) and the necessity of the center of rotation being precisely determined. Experimental results show that the algorithm still effectively functions even when the rotation angle reaches18°. Also, the average PSNR is raised approximately 26dB after stabilization.

Key words: electronic image stabilization, large rotation, corner matching, global motion estimation
