/** @brief Restores the selected region in an image using the region neighborhood.
@param src Input 8-bit 1-channel or 3-channel image.
@param src Input any 1-channel or 8-bit 3-channel image.
@param inpaintMask Inpainting mask, 8-bit 1-channel image. Non-zero pixels indicate the area that
needs to be inpainted.
@param dst Output image with the same size and type as src .
