METHOD FOR GENERATING SIDE INFORMATION WHICH CORRECTS A MOTION FIELD ERROR OF DISTRIBUTED VIDEO CODING AND A DVC DECODER USING THE SAME, CAPABLE OF INCREASING COMPRESSION PERFORMANCE BY REDUCING THE BIT RATE OF THE DVC

摘要

PURPOSE: A method for generating side information which corrects a motion field error of distributed video coding and a DVC decoder using the same are provided to move the location of a motion compensation block corresponding to an error of a motion field, thereby increasing the accuracy of a current frame predictive result.;CONSTITUTION: A motion field is extracted based on a block between a past frame and a future frame(S41). The location of a motion compensation block changes depending on an error of the motion field(S42). Motion compensation is performed based on the new location of the motion compensation block(S43). The location of the motion compensation block moves to position the motion field on the center of the motion compensation block of a current frame.;COPYRIGHT KIPO 2010
