| 摘 要： | 本文提出一种既可用于从图象上提取具有某种用途的一维边缘,又可用于提取具有多种用途的二维边缘的序贯一维型边缘检测新算法。由于构成该算法重要组成部分的基础算子的作用,以及将二维问题化为一维问题求解而使其明显具有简单,快速、有效的特点。该算法还具有Abdou [1] 等所建议的边缘检测算子应具有的两个特性。

| Abstract: | A new sequential 1-D algorithm is presented in this paper. This new algorithm can be used for extracting not only 1-D edges for a certain purpose but also 2-D edges with maltipurpose applications. Because of the use of a "ground operator", which is an important component in this algorithm and also the use of 1-D method instead of 2-D, the algorithm is very simple, effective, and the performance is very fast. Besides, this algorithm also possesses the two desirable characteristics of an edge detector as suggested by Abdou et al. |
