c++ - 如何将 3 个 opencv IplImage 合并为一个？

Question

所以我有这样的代码:

    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 连接回某个 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.

编辑:

来自文档:您必须调用:

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

假设您的目标图像也只有 3 个 channel 。
