摘 要: | 考虑到边缘局部相关性的特点,提出了一种新的边缘评价方法。该方法不需要标准边缘图,直接对边缘图求取总的边缘点数(A)、4-连通成分数(B)、8-连通成分数(C)以及它们之间比值(C/A、C/B),并进行综合评价。实验结果表明,该评价方法实用性强,具有一定的参考价值。

Abstract: | With the characteristics of edge partial correlation in mind, the authors put forward in this paper a new edge evaluation method. This method needs no standard edge diagram, and can directly figure out number of total edge points (A), number of 4-connection components (B) and number of 8-connection components (C) as well as their ratios (C/A and C/B) relative to the edge diagram, thus making an integrated evaluation. With strong practical applicability, this method has some referential significance. |
