Simulation of Wyner-Ziv Video Coding Algorithm Based on Transform Domain
The Wyner-Ziv viden coding scheme based on transform domain is researched in this paper.Firstly,the background and basic theories of DVC(Distributed Video Coding)are simply introduced,especially on the theories of Wyner-Ziv(a Iossy coding theory of side information on the decoder).Further more,referring to the basic Wyner-Ziv coding scheme,a novel tran.sform domain Wyner-Ziv coding scheme is designed.This method realizes video compression by intra-frame encoding and inter-frame decoding.and uses difierent codec for different date type.In the specific type codec.the transform coefficients of a Wyner.Ziv frame are encoded independently using a scalar quantizer and hamming code encoder.At the decoder,in order to construct the side information for Wyner-Ziv frame decoding,the motion compensates interpolation.And then the ideal decoded frames are obtained by combining the side information with the Wyner-Ziv frame.Finally,the related simulation and analysis aregiven.
