Given a background image $($input $1)$ with some area of pure green $([[0,255,0]])$ on it$,$

first resize the image of the foreground $($input $2)$ to the same dimensions as the background

image. Then, mask out the area of the background image corresponding to the green area,

and replace it with the corresponding area of the image of the foreground. The
