Abstract
In asymmetric stereoscopic video coding, one view is coded in a quarter of the resolution of the other and the low- resolution view is predicted from the high-resolution view. This way, stereoscopic video effect could be achieved with only moderately increased bandwidth and complexity. Inter-view prediction tools for generating the predictor of a maroblock (MB) or MB partition in the low-resolution view from the high-resolution view play a vital role for coding efficiency in asymmetric video coding. In this paper, we propose a method that applies an adaptive filter to generate picture-level adaptive inter-view predictors for MBs or MB partitions. At the encoder, a low complexity preprocessing module is built to find out the filters. Simulation results show that the proposed method provides a bit-rate saving of 26% at maximum and 5% on average.
