OpenCV提取显示一张图片的R,G,B颜色分量调试记录

使用OpenCV可以提分别提取显示一张图片（或者视频）的R,G,B颜色分量。代码如下。

// ConsoleApplication1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "cv.h"  
#include "highgui.h" 
//#include  
#include  
#include 

#pragma warning(disable:4996)

int _tmain(int argc, _TCHAR* argv[])
{
	IplImage *img = cvLoadImage("test.bmp", 1);
	IplImage *channel_r = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage *channel_g = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage *channel_b = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 1);
	IplImage *img_r = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 3);
	IplImage *img_g = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 3);
	IplImage *img_b = cvCreateImage(cvGetSize(img), IPL_DEPTH_8U, 3);

	cvSplit(img, channel_b, channel_g, channel_r, NULL);
	cvMerge(channel_b, 0, 0, 0, img_b);
	cvMerge(0, channel_g, 0, 0, img_g);
	cvMerge(0, 0, channel_r, 0, img_r);

	cvNamedWindow("ImageOrigin", CV_WINDOW_AUTOSIZE);
	cvNamedWindow("Image_R", CV_WINDOW_AUTOSIZE);
	cvNamedWindow("Image_G", CV_WINDOW_AUTOSIZE);
	cvNamedWindow("Image_B", CV_WINDOW_AUTOSIZE);
	cvShowImage("ImageOrigin", img);
	cvShowImage("Image_R", img_r);
	cvShowImage("Image_G", img_g);
	cvShowImage("Image_B", img_b);

	cvSaveImage("img_red.bmp", img_r);
	cvSaveImage("img_green.bmp", img_g);
	cvSaveImage("img_blue.bmp", img_b);

	cvWaitKey(0);
	cvReleaseImage(&img);
	cvReleaseImage(&img_r);
	cvReleaseImage(&img_g);
	cvReleaseImage(&img_b);
	cvDestroyAllWindows();
}

遇到下面问题：

缺少相应的dll动态库文件，加入相应的动态库

输出如下错误：

缺少bmp文件加入相应的文件

程序运行结果如下：

r

g：

b：
