Texture denoising utilized in depth-enhanced multiview video coding

In this study, we applied a locally adaptive filtering in 3D DCT domain to 3 views as a preprocessing stage for encoding. Afterwards, these views were encoded and the decoded views were used by a Depth-Image-Based Rendering algorithm (DIBR) to produce virtual intermediate views. A stereopair at a suitable separation for viewing on a stereoscopic display was selected among the synthesized views. A large-scale subjective assessment of the selected synthesized stereopair was performed. A bitrate reduction of 9% on average and up to 21.8% was achieved with almost no penalties on subjective perceived quality.
