摘要: 利用链编码及其特性,分析得出图像区域边界的周长、最小外接矩形(MER)的长与宽,及图像所占区域的面积.对于正四边形、正三边形和正六边形点阵上的图形,分别提出了直接从链编码计算图像顶点欧氏距离的方法.

Abstract: This paper introduces the way of utilizing VCC to get the perimeter of an image region, the length and width of the minimum external rectangular (ab. MER) of the image and the size of the region occupied by the image. For digital images in square, triangular and hexagonal lattices, formulates respectively the methods of calculating the Euclid distance from vertex-chain-code of the region boundary.

Key words: coordinate-labeling-automata, Euclidean distance, VCC, coordinate-labeling-automata, Euclidean distance
