본 논문에서는 H.264/AVC 코딩 효율 향상을 위해 잔차 블록의 상관관계에 기반한 대체 변환을 제안한다. 신호의 상관 계수가 -0.5 ~ 0.5 범위에 있을 때 신호의 에너지를 크게 압축하기 위해 이산 사인 변환과 이산 코사인 변환이 교대로 사용됩니다. 따라서 H.264/AVC에서는 이산 사인 변환과 이산 코사인 변환을 함께 사용하는 것이 제안된다. 율-왜곡 최적화를 이용하여 두 변환 사이에서 최적의 변환을 선택하는 대체 변환은 H.264/AVC와 비교하여 코딩 이득을 보여준다. 제안된 방법은 상대적으로 높은 비트레이트에서 JM 1.0에 비해 최대 10.2dB의 PSNR 이득을 달성한다.

Abstract: In this paper, an alternative transform based on the correlation of the residual block is proposed for the improvement of the H.264/AVC coding efficiency. A discrete sine transform is used alternately with a discrete cosine transform in order to greatly compact the energy of the signal when the correlation coefficients of the signal are in the range of -0.5 to 0.5. Therefore, the discrete sine transform is suggested to be used in conjunction with the discrete cosine transform in H.264/AVC. The alternative transform selecting the optimal transform between two transforms by using rate-distortion optimization shows a coding gain compared with H.264/AVC. The proposed method achieves a PSNR gain of up to 1.0 dB compared to JM 10.2 at relatively high bitrates.

AB - In this paper, an alternative transform based on the correlation of the residual block is proposed for the improvement of the H.264/AVC coding efficiency. A discrete sine transform is used alternately with a discrete cosine transform in order to greatly compact the energy of the signal when the correlation coefficients of the signal are in the range of -0.5 to 0.5. Therefore, the discrete sine transform is suggested to be used in conjunction with the discrete cosine transform in H.264/AVC. The alternative transform selecting the optimal transform between two transforms by using rate-distortion optimization shows a coding gain compared with H.264/AVC. The proposed method achieves a PSNR gain of up to 1.0 dB compared to JM 10.2 at relatively high bitrates.
