【摘要】 提出一种基于松弛法的影像边缘提取算法．本文详述了边缘标号的设置及初始概率的计算，并根据邻域内的信息分布，综合考虑了边缘的先验知识，设计出自适应的支持函数．更多还原

【Abstract】 This paper puts forward a method based on relaxation.Using edge labeling.edges oh the image can be acquired through several iterations. According to the information distributionof the neighbour and prior knowledge of edges,self-adapting support function has been constructed.更多还原
