Abstract

Many important alpha matting algorithms are proposed in recent years, which focus on how to solve the alpha value on image interactively. However, few papers discuss about why the border of opaque object in image is half-transparent. In this paper, we show how the optical principles produce the translucent effect on photography. We denote the matting problem in a unified form, by which form, we can analyze and compare different matting algorithm by comparing their sampling function and matting matrix. Our work can help us to propose and evaluate new matting algorithm. We also expand our framework to video matting and get an enhanced video matting algorithm.
