图像分割之（五）OpenCV的GrabCut调用
在OpenCV的源码目录的samples的文件夹下，有grabCut的使用例程，请参考：
opencv\samples\cpp\grabcut.cpp。
在这里给出最简单的调用grabcut
#include <cv.h>#include <highgui.h>#pragma comment(lib,"cv210d.lib")#pragma comment(lib,"cxcore210d.lib")#pragma comment(lib,"highgui210d.lib")#include <iostream>using namespace std;using namespace cv;void MyShowImage(Mat Image,const string winName){imshow( winName, Image );}void getBinMask( const Mat& comMask, Mat& binMask ){ binMask.create( comMask.size(), CV_8UC1 ); binMask = comMask & 1;}int main( int argc, char** argv ){ Mat image = imread( "lena.jpg", 1 );const string winName = "image";MyShowImage(image,winName);/***********************************/Mat bg;Mat fg;Rect rect = Rect(47,48,408,464);Mat mask,res;mask.create( image.size(), CV_8UC1); grabCut( image, mask, rect, bg, fg, 1, 0 );Mat binMask;getBinMask( mask, binMask ); image.copyTo( res, binMask );MyShowImage(res,winName);/***********************************/cvWaitKey(0); return 0;}
