Wavelet Scalable Video Coding with Minimal Average Temporal Distance for Motion Estimation
Wavelet scalable video coding (WSVC) can be used efficiently for scalable mesh compression for virtual reality applications over IP networks. This paper proposes efficient methods to improve the coding efficiency of WSVC through the minimization of average temporal distance (ATD) for motion estimation. The ATD is closely related to the peak signal-to-noise ratio (PSNR) performance of WSVC which is based on motion compensated temporal filtering. Simulation results show that the proposed methods with minimum ATD give about 1 to 2dB PSNR improvements compared to the conventional WSVC.
