cvMerge Method (src0, src1, src2, src3, dst)
NamespacesEmgu.CVCvInvokecvMerge(IntPtr, IntPtr, IntPtr, IntPtr, IntPtr)

This function is the opposite to cvSplit. If the destination array has N channels then if the first N input channels are not NULL, all they are copied to the destination array, otherwise if only a single source channel of the first N is not NULL, this particular channel is copied into the destination array, otherwise an error is raised. Rest of source channels (beyond the first N) must always be NULL. For IplImage cvCopy with COI set can be also used to insert a single channel into the image.
