Depth map is widely adopted and available in the 3D research area. Combining the depth map with the matting techniques is helpful to the original matte and depth image based rendering in 3D. Herein, in this paper, a novel adaptive depth map assisted matting approach with concise integration is presented and applied to achieve favorable matting results. In this approach, the Lagrange-multiplier-free closed form solution is firstly derived to reduce the computation complexity and to increase matting accuracy. Based on the work of Levin et al. on closed form matting, an improved alpha matte is then achieved by introducing an adaptive smoothness criterion which is the function of depth map variance. Finally, the matting system is capable of working in a full automatical way by generating the trimap from the depth information. Simulation results demonstrate that the proposed method is able to efficiently generate an alpha matte with an roughly user specified scribbles or an automatically generated trimap. |
