我是64位的机器，但是我用的32位的配置，有这个函数我这么写的：







#include "stdafx.h"

#include <iostream>

#include <vector>



#include "opencv2/core/core.hpp"

#include "opencv2/highgui/highgui.hpp"

#include "opencv2/imgproc/imgproc.hpp"



#include <cv.h>

#include <highgui.h>



using namespace std;

using namespace cv;



#pragma comment(lib,"opencv_highgui244d.lib")

#pragma comment(lib,"opencv_core244d.lib")

#pragma comment(lib,"opencv_imgproc244d.lib")

void split_image(const char* image_name)

{

	Mat image_src = imread(image_name);

	Mat image_dst;

	vector<Mat> bgr;



	//颜色通道分离

	//输入图像

	//分离后各通道

	split(image_src,bgr);



	//颜色通道合成

	//输入各通道

	//输入图像

	merge(bgr,image_dst);

	



	//用彩色图像形象的表示一下,除了原通道保留，其余两通道置0

	Mat tmp(image_src.size(),CV_8U,Scalar(0));

	vector<Mat> b,g,r;   //用来表示的彩色图像



	for(int i=0;i<3;i++)

	{

		if(i==0)

			b.push_back(bgr[0]);

		else

			b.push_back(tmp);



		if(i==1)

			g.push_back(bgr[1]);

		else

			g.push_back(tmp);



		if(i==2)

			r.push_back(bgr[2]);

		else

			r.push_back(tmp);

	}

	Mat image_b,image_g,image_r;

	

	merge(b,image_b);

	merge(g,image_g);

	merge(r,image_r);



	namedWindow( "b", CV_WINDOW_AUTOSIZE );

	namedWindow( "g", CV_WINDOW_AUTOSIZE );

	namedWindow( "r", CV_WINDOW_AUTOSIZE );

	namedWindow( "dst", CV_WINDOW_AUTOSIZE );

	imshow("b",image_b);

	waitKey(1);

	imshow("g",image_g);

	waitKey(1);

	imshow("r",image_r);

	waitKey(1);

	imshow("dst",image_dst);

	moveWindow("dst", 1,1);

	moveWindow("b",800,1);

	moveWindow("g",1,500);

	moveWindow("r",900,500);



	waitKey(1);





	waitKey(0);

	//不加上面两个的话，窗口显示出来有问题，不能移动，鼠标处于忙碌状态。而且还要跟imshow配对



}

int _tmain(int argc, _TCHAR* argv[])

{

	char* image_name = "swan.jpg";

	split_image(image_name);

	//split_image_gray(image_name);

	//historgram_channel(image_name);



	



	getchar();

	return 0;

}
