Abstract

This paper describes a skipping method for handling various illuminating effects in video sequences. The weighted prediction in H.264/AVC improves coding efficiency and image quality. However, it requires massive computation overheads for entire system, and thus, reducing the computation complexity becomes more important. Compared to the weighted prediction method in the H.264/AVC, the proposed method can decrease the bitrate down to 15%. Moreover, the proposed algorithm can reduce computation complexity down to 30%, compared to the localized weighted prediction which does not skip unnecessary calculation.

이 논문은 영상내의 다양한 발광 효과를 선택적으로 다루기 위한 가중치 예측 생략 방법을 다루고 있다. 가중치 예측은 부호화 효율과 영상의 화질을 개선시키는 데에 지대한 역할을 하고 있으나, 방대한 연산 량으로 인해 실제로 구현하기 어려운 제점이 있다. 제안한 기술은 JM 표준의 가중치 예측에 비해 약 15%의 비트 율을 감소시키면서 지역적인 가중치 예측에 비해 30%의 연산 량을 감소시켰다.
