초록

본 논문은 H.264/AVC 의 효율적 모드 결정을 위한 율 왜곡 예측 방법을 제안하였다. 제안한 방법에서 모드 결정은 DCT 계수의 라플라시안 분포 모델링을 적용하여 비트율을 예측함으로서 양자화와 엔트로피 부호화의 과정이 불필요하다. 실험결과, 실제 율-왜곡치와 제안한 방식과의 율-왜곡치가 거의 일치하였고, 기존의 방식보다 0.02 dB의 PSNR 이득을 보였다.

This paper presented a rate-distortion estimation method for effective mode decision in H.264/AVC. In this approach, in order to decide a mode, laplacian distribution modeling of DCT coefficients is utilized, which do not need to such process as quantization, entropy coding. From the simulation results, proposed a method showed that rate-distortion between proposed scheme and practical value was almost the same and performed 0.02dB of PSNR gain.
