Abstract

In view of the problem that the traditional sub pixel edge extraction method is obviously deviated from the real edge near the corner. A new algorithm is proposed. In this paper, the corner protection function is added to the level set energy functional, which makes that the evolution of level set function is restricted at the corner, therefore this algorithm can improve the accuracy of edge extraction near the corner. The sub pixel edge extraction results of simulated and real images show that the proposed method is more accurate at the edge of the corner.
