| 摘 要： | 研究了针对不同边缘类型进行同步亚像素级检测的问题.通过详细分析3种基本边缘类型(阶跃型边缘、脉冲型边缘、屋脊型边缘)的特点,提出了一种基于形体质心思想的通用算法,并对其进行了严格证明.该算法能同时对这3种基本类型边缘进行亚像素级检测与定位,且不存在原理性误差.对算法进行离散化处理,给出了便于计算机实现的离散算法.通过实验验证了此算法的有效性,并分析了误差产生的原因.

| Abstract: | The problem for detecting all types of edge with a same method at subpixel level was researched.A novelty universal algorithm for subpixel edge detection based on figure centroid was proposed by analyzing the characteristics of three basic types of edge(step edge,pulse edge,roof edge).It can process all types of edge at one time.The algorithm was demonstrated,and it was illuminated no error theoretically.Afterward discrete form of the algorithm was deduced for calculating on computer.Finally,validity of the algorithm was testified by preliminary experiments in noise and no noise situation,and the reason of making error was analyzed. |
