Title
Progressive Side Information Refinement with Non-local Means Based Denoising Process for Wyner-Ziv Video Coding
Abstract
On the basis of a non-local means denosing process, a novel progressive side information refinement framework for a transform domain Wyner-Ziv video codec is proposed, where the side information is progressively improved, as the decoding proceeds, by exploring both temporal-spatial similarities and already decoded DCT bands. Simulation results show up to 2.5dB in RD performance gain against that of the same codec without including the proposed side information refinement framework for sequences with high motion and/or large group-of-picture sizes. Moreover, the proposed framework adds no significant complexity to the decoder, and even results in a decoding speed-up due to the less required error correcting iterations, for most of the test sequences.
