Copies selected elements from input array to output array: dst(I)=src(I) if mask(I)!=0. If any of the passed arrays is of IplImage type, then its ROI and COI fields are used. Both arrays must have the same type, the same number of dimensions and the same size. The function can also copy sparse arrays (mask is not supported in this case).
