Abstract: Image matting is a process of extracting a foreground object from an image. Providing trimap is an important challenge of image matting. An attentively created trimap is required to get accurate alpha-matte. Accuracy of trimap-based approach reduces drastically as the trimap becomes thicker and coarser. Providing trimap manually is an exhausting and time consuming task for user. Scribble-based approach solves the problem by reducing user effort but with reduced accuracy. In this paper, we propose an approach to automatically generate trimap. It uses learning-based matting to generate a high quality alpha-matte in less time. It helps in obtaining accurate and fast result without user effort. The experimental results show the automatically generated trimap and alpha-matte are qualitatively and quantitatively better.
