New data formats that include both video and the corresponding depth maps, such as multiview plus (MVD), enable new applications in which intermediate views (virtual views) can be generated using transmitted/stored (reference maps inputs. We propose a map coding method based on distortion measurement by deriving relationships between distortions coded rendered view. In our experiments we use codec H.264/AVC tools, where rate-distortion (RD) optimization for encoding makes of metric. Our...

In order to improve 3D video coding efficiency, we propose methods estimate rendered view distortion in synthesized views as a function of the depth map quantization error.

Depth map compression is important for compact "texture-plus-depth" representation of a 3D scene, where texture and depth maps captured from multiple camera viewpoints are coded into the same format. Having received such format, decoder can synthesize any novel intermediate view using two neighboring views via depth-image-based rendering (DIBR). In this paper, we combine previously proposed techniques that promote sparsity in transform domain coding gain-graph-based (GBT) sparsification...

Video coding in the YCbCr color space has been widely used, since it is efficient for compression, but can result distortion due to conversion error. Meanwhile, RGB maintains high fidelity, having drawback of a substantial bitrate increase with respect coding. Cross-component prediction (CCP) efficiently compresses video content by decorrelating components while keeping fidelity. In this scheme, chroma residual signal predicted from luma inside loop. This paper gives description CCP scheme...

The screen content coding (SCC) Extensions of high efficiency video (HEVC) employs in-loop adaptive color-space transform (ACT) technique to explore the inter-color-component redundancy, i.e., statistical redundancy among different color components. In ACT, prediction residual signal is adaptively converted into a space, YCgCo. rate-distortion criteria employed decide whether code in original space or YCgCo space. Typically, correlation could be reduced when ACT enabled. after possible...
