Matting is a fundamental computer vision problem, which has wide applications from daily life to professional fields. To get more precise matting result, we propose a deep learning based algorithm. The network called very deep residual network (VDRN). The first stage is designed to capture entire foreground object by an improved encoder-decoder architecture. It consists of a deep residual encoder and a sophisticated decoder. The second stage is a fully residual convolutional network used for recovering fine structure like hair. Experimental results show our algorithm can tackle complicated foreground textures even it has similar color with background. We evaluate our algorithm on alphamatting.com online benchmark, and Composition-1k dataset. The results demonstrate our method outperforms previous methods, especially in tackling fine structure.
