Robust View Interpolation with Mesh Cutting

Abstract

Existing view interpolation methods like DIBR require accurate disparity map which greatly limits their applications. To this aim, we propose a novel mesh-based view interpolation algorithm capable of synthesizing visually coherent virtual views with rough disparity map estimated by stereo matching algorithms. We adopt an edge-aware mesh cutting method to explicitly handle occlusion and preserve sharp depth discontinuities. Experiments on Middlebury dataset and 3D-HEVC test sequences demonstrate that proposed method outperforms DIBR and state-of-the-art mesh-based view interpolation algorithm in terms of visual quality and PSNR.
