3D-HEVC Neighboring Block Based Disparity Vector (NBDV) Derivation Architecture: Complexity and Implementation Analysis

摘要

HEVC (High Efficiency Video Coding), the state-of-the-art video coding standard has 3D extension known as 3D-HEVC, which is established by JCT-3V. In current design of 3D-HEVC, to exploit the redundancies of the 3D video signal, various tools are integrated. In 3D-HEVC, the neighboring block disparity vector (NBDV) mode is used to replace the original predicted depth map (PDM) for interview motion prediction. A new estimated disparity vector depth oriented neighboring block disparity vector (DoNBDV) is used to enhance the accuracy of the NBDV by utilizing the coded depth map. In this paper, the complexity and implementation analysis of the NBDV and DoNBDV architectures are analyzed in terms of performance, complexity, and other design considerations. It is hence concluded that NBDV and DoNBDV for 3D-HEVC video signals provide attractive coding gains with comparable complexity as traditional motion/disparity compensation.
