Enhancements of Representation and Interactivity for Multi-view Video Based on Layered Depth Image

The feature of rendering arbitrary view make layered depth image (LDI) be able to present multi-view video data and provide enhanced interactivity, such as free view video (FVV). However, visual artifacts occurred in the rendered result limit the practicality of LDI. In this paper, we proposed an approach to deal with this problem, which refines colors of the depth pixels by clustering to remove matting effects during generating of LDI, and applies median filter to rendered result to remove the gaps or holes caused by disocclusion and undersample. Experimental results show that our approach is practicable and efficient.
