| Abstract: | Weighted prediction and illumination compensation are key technologies for inter prediction in a video codec. They increase coding efficiency when the brightness of objects in a sequence fluctuates. Since most conventional methods compensate for illumination changes at slice-level, they are not effective to code general sequences which have no illumination change. Proposed is a pixel based illumination compensation (PBIC) scheme which is applied to the selected pixels adaptively. The optimal IC parameters are calculated considering characteristics of each block whereas parameters of the conventional schemes are optimised for a slice. From the simulation results, it is concluded that the proposed PBIC improves the coding efficiency of high efficiency video coding (HEVC). [ABSTRACT FROM AUTHOR] |
