I just want to restore the black area with the original image.

Answer 1

As I know binary images are stored in grayscale in opencv values 1-->255.

To create „dummy“ RGB images you can do: rgb_img = cv2.cvtColor(binary_img, cv.CV_GRAY2RGB)

I call them „dummy“ since in these images the red, green and blue values are just the same.
