In this paper, we consider the embedding of a complete binary tree in a star graph with the objective of minimizing congestion and dilation. We develop two embeddings: (i) a congestion-free, dilation-2, load-1 embedding of a level- p binary tree, and (ii) a congestion-free, dilation-...
Description: A faster implementation of binary dilation and erosion. Our functions take advantage of MATLAB s decomposition of the structuring element but they may result much faster. Try to run example.m to see the speed improvement factor, changing the parameters. ...

膨胀膨胀(dilation)(dilation) 简单膨胀是将与某物体接触的所有背景点合 并到该物体中的过程。过程的结果是使物体的面积增大了相 应数量的点。如果物体是圆的,它的直径在每次膨胀后增大 两个像素。如果两个物体在某一点相隔少于三个像素,它们 将在该点连通起来(合并成一个物体)。膨胀在填补分割后 物体中的空洞...
