Python | Extracting foreground to image using Grabcut algorithm

Foreground Extrac is any method that allows the foreground of an image to be extracted for further processing like object recognition, tracking, etc. The algorithm used to extract the foreground is here GrabCut algorithm. In this algorithm, an area is drawn according to the foreground, a rectangle is drawn above it. This is the rectangle that surrounds our main object. The coordinates of the region are determined by the foreground mask. But this segmentation is not ideal as it can mark some foreground as background and vice versa. This problem can be avoided manually. This foreground extraction technique functions like a green screen in cinematography.
