有时候要将二值化图像中最大的连通域保存下来.以下函数提供了一种方法: %function [img]=maxLianTongYu(I):求图像中最大的连通域 %输入:I 输入图像 %输出:img 仅包括最大连通域的图像 function [img]=maxLianTongYu(I) if length(size(I))>2 I = rgb2gray(I); end if ~islogical(I) imBw = im2bw(I); %转换为二值化图像 else imBw = I; end imB…
Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. Example 1: 0 3 | | 1 --- 2 4 Given n = 5 and…
