1. matlab函数bwareaopen──删除小面积对象格式:BW2 = bwareaopen(BW,P,conn)作用:删除二值图像BW中面积小于P的对象,默认情况下使用8邻域.算法:(1)Determine the connected components. L = bwlabeln(BW, conn);(2)Compute the area of each component. S = regionprops(L, 'Area');(3)Remove small objects.

寻找包裹轮廓的最小正矩形:boundingRect 函数 返回矩阵应满足:① 轮廓上的点均在矩阵空间内.② 矩阵是正矩阵(矩形的边界与图像边界平行). Rect boundingRect(InputArray points); 唯一一个参数是输入的二维点集,可以是 vector 或 Mat 类型. 代码示例: #include<opencv.hpp> #include<iostream> using namespace cv; using namespace std; int ma
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
