如何將3個cv IplImages打開成一個？

Question

所以我有這樣的代碼：

IplImage* redchannel = cvCreateImage(cvGetSize(destination), 8, 1); 
        IplImage* greenchannel = cvCreateImage(cvGetSize(destination), 8, 1); 
        IplImage* bluechannel = cvCreateImage(cvGetSize(destination), 8, 1); 
cvSplit(source, bluechannel, greenchannel, redchannel, NULL); 
// code... 
//now I need to join them back 

如何加入bluechannel，greenchannel和redchannel回一些的IplImage *目的地是哪裏？

Answer 1

void cvMerge（const CvArr * src0，const CvArr * src1，const CvArr * src2，const CvArr * src3，CvArr * dst）;

Here is the documentation.

編輯：

從文檔： 你將不得不撥打：

cvMerge(bluechannel, greenchannel, redchannel, NULL, target); 

假設你的目標圖像也只有3個頻道。
