As the latest 3D video coding standard, 3D High Efficiency Video Coding (3D-HEVC) achieves efficient coding. Depth coding plays an important role in 3D-HEVC. For better prediction of edges in depth maps, new depth intra modes were proposed, such as Depth Modeling Modes (DMMs). DMM Mode 1, namely explicit wedgelet signalization mode, can improve the performance of synthesized views, but leads to unaffordable...
In this paper, we present a novel rate control method with optimized region-based bit allocation for depth video coding. First, a synthetic view distortion oriented segmentation method is proposed to divide depth video into different regions, including texture areas and smooth areas. Then, the expanded exponential distortion-rate (D-R) models and power quantization parameter-rate (QP-R) models are...
As a substitute to discrete cosine transform (DCT), a more complicated transform scheme has been adopted in H.264/AVC and inherited by H.264/SVC. For supporting the scalability, H.264/SVC incorporates the inter-layer prediction mechanisms, which lead to the variety of the composition of residual frame as the input of the transform. However, so far scarcely any study has been carried out on the transform...
A novel rate control scheme for H.264/SVC base layer is presented in this paper. At first, a new mean-absolute-difference (MAD) estimation method is introduced to replace the traditional MAD linear prediction model. This new method could reduce the computation complexity sharply and decrease the MAD estimation error by up to 35.6%. Then, the quadratic rate quantization (R-Q) model and the linear R-Q...
