概要

This letter introduces a cost-effective chrominance compensation scheme. The proposed method is applied to both ‘INTER 16 × 16’ and ‘SKIP’ modes in only anchor P-pictures. By testing using JVT common test condition, simulation results show that proposed method can obtain average BD-PSNR gains for U and V as 0.14dB and 0.13dB, respectively while maintaining almost the same BD-PSNRs for Y. For the range of low bit-rate, it is observed that average BD-PSNR gains for Y, U and V are 0.14dB, 0.49dB and 0.53dB, respectively. Necessary computational complexity is very marginal because the number of anchor P-pictures is very small in comparison with whole coded video sequences. However it can be found that the proposed method can significantly improve the coding efficiencies of color components.
