Can you create a c++ program to overlay 2 BMP format images using opencv with this algorithm:

if a pixel is black in the overlay image, the corresponding pixel in out1 is white. If a pixel is not black in the overlay image, the corresponding pixel in out1 equals the corresponding pixel in the original image. We will call this way of processing image overlay (IO).

Images of any size up to 1024x768 pixels
