主要回顾了图象边缘检测技术的发展历程,讨论了一些典型的边缘检测算法的特点,分析了他们的机理和优劣,并对边缘检测算法的研究方向进行展望-Edge detection is an indispensable step before image analysis and recog nit ion, and is an important technology in the image preprocessing procedure. In this paper w e chiefly review the study of the edg e detec


t ion methods , and then disgus s the characterist ic of some typical edge detect ion algorithms, analyze thei r

qualities, and final ly give the development of edge detect ion methods in the future.
