Compression-Induced Rendering Distortion Analysis for Texture/Depth Rate Allocation in 3D Video Compression
Compression-Induced Rendering Distortion Analysis Texture/Depth Rate Allocation 3D Video Compression
2009/12/31
In 3D video applications, the virtual view is generally rendered by the compressed
texture and depth. The texture and depth compression with different bit-rate overheads can lead to different virtual...
