Rectification-Based View Interpolation and Extrapolation for Multiview Video Coding
Xiaoyu Xiu, Delong Pang, Jie Liang · IEEE Transactions on Circuits and Systems for Video Technology · 2011
In this paper, we first develop improved projective rectification-based view interpolation and extrapolation methods, and apply them to view synthesis prediction-based multiview video coding (MVC). A geometric model for these view synthesis methods is then developed. We also propose an improved model to study the rate-distortion (R-D) performances of various practical MVC schemes, including the current joint multiview video coding standard. Experimental results show that our schemes achieve superior view synthesis results, and can lead to better R-D performance in MVC. Simulation results with the theoretical models help explaining the experimental results.
