Natural Image Matting using HSI framework

Natural Image Matting today, is widely used in various disciplines including media, animation industry, computer simulations for research etc. The process of estimating the foreground and background colors with proper alpha mattes has been widely studied and satisfactory results have also been obtained. This paper deals with one such method where a rough estimate of alpha matte in RGB (Red, Green, Blue) framework is made and finally it is refined in the HSI (Hue, Saturation, Intensity) framework.
