OpenCV OTSU大津法

直接上代码的才实在啊~

//视频流大津法
#include "opencv2\opencv.hpp"
#include <iostream>
using namespace std;
using namespace cv;
int main(){
	VideoCapture capture(0);
	bool stop(false);
	Mat frame;
	Mat result;
	Mat frame_gray;
	while (!stop)
	{
		if (!capture.read(frame))//读取视频帧
		{
			break;
		}
		cvtColor(frame, frame_gray, COLOR_BGR2GRAY);//图像灰度化
		threshold(frame_gray, result, 0, 255, CV_THRESH_BINARY | CV_THRESH_OTSU);//大津法
		imshow("大津法", result);
		waitKey(33);
	}
	waitKey(0);
	return 0;
}
