Abstract: In this paper, a novel edge-detecting algorithm is proposed. Different from other approaches, it starts from the characteristics of image edges. As a theory foundation, a serial of edge point constraints are first defined, and then it solves these constraints with the knowledge of set theory. As the foundation is constructed, the new algorithm is put forward successfully. Practices show that this new algorithm works effectively and produces good edges.
