Abstract: This paper analyzes the theory of Harris operator, and points out its disadvantage. It proposes an auto-adaptive Harris operator based on the ideology of image break and neighboring point eliminating method. It makes the corners are well-proportioned distributing, and avoids too many corners stay together effectively. Experimental results show that the algorithm can detect corner more reasonable, and can be used in image mosaics well.
