Comment rejoindre 3 open cv IplImages en un?

Question

J'ai le code comme:

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 

Comment rejoindre bluechannel, greenchannel et redchannel de nouveau dans une IplImage * destination?

Answer 1

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

Here is the documentation.

Edit:

De la documentation: Vous devrez appeler:

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

En supposant que votre image cible a aussi seulement 3 canaux.
