Digital image matting is a well-known computer vision problem. It refers to the problem of extracting the region of interest such as foreground object from an image based on user inputs like scribbles or trimap. In the images shown below, figure (1) is the original user input and we want to extract the object of interest (two horses in this case), then blend the object into a new scene as shown in figure (3). Figure (2) shows the aplha matte which is a gray-scale image with pixel value lies between 0 and 1 indicating the transparency or opacity.
