如何将3个opencv Ipl图像合并为一个？

Question

所以我的代码如下：

    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

如何将bluechannel，greenchannel和redchannel加入一些IplImage *目的地？

Answer 1

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

Here is the documentation.

修改

从文档中： 你必须打电话：

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

假设您的目标图片也只有3个频道。
