基于opencv实现图像RGB分离

开发环境：VS2013+opencv3.0

#include
using namespace std;
using namespace cv;
int main()
{

	Mat InpImage = imread("test.jpg", -1);
	Mat bgr[3];
	Mat bgr_res[3];
	for (int j = 0; j < 3; j++)
	{
		split(InpImage, bgr);
		for (int i = 0; i<3; ++i)
		{
			if (i != j)
				bgr[i] = Mat::zeros(InpImage.size(), bgr[0].type());
		}
		merge(bgr, 3, bgr_res[j]);
	}

	imshow("b", bgr_res[0]);
	imshow("g", bgr_res[1]);
	imshow("r", bgr_res[2]);


	imshow("原始图像", InpImage);
	waitKey(0);
	return 0;
}

效果：
