Opencv2.4学习::二值化(2)threshold

二值化系列:

(1)OTSU算法

(2)固定二值化

(3)自适应二值化

比较简单,直接使用即可 

#include<opencv2/imgproc/imgproc.hpp>
#include<opencv2/highgui/highgui.hpp>
#include<iostream>
using namespace std;
using namespace cv;
int main()
{
	Mat srcImage = imread("F:\\opencv_re_learn\\2.jpg");
	if (!srcImage.data){
		cout << "failed to read" << endl;
		system("pause");
		return -1;
	}
	//conver to gray
	Mat srcGray;
	cvtColor(srcImage, srcGray, CV_BGR2GRAY);
	Mat dstImage;
	//初始化阈值参数
	int thresh = 120;
	/*0:二进制阈值  1:反二进制阈值  2:截断阈值    3:0阈值  4:反0阈值*/
	int thresType = 0;
	//预设最大值
	const int maxVal = 255;
	//阈值化
	threshold(srcGray, dstImage, thresh, maxVal, thresType);
	imshow("thres_result", dstImage);
	waitKey(0);
	return 0;
}
