Abstract

This papers proposes a motion vector coding method which selects the optimal predictive motion vector after excluding some candidate predictive motion vectors in the minimum rate-distortion sense, and prunes the candidate predictive motion vectors by a contradiction testing that operates under a predefined criterion at both encoder and decoder for reducing the signaling information. Experimental results show that the proposed method gains in BDBR by up to 1.8% compared to the H.264/AVC.

본 논문은 에러 발생 가능한 예측 움직임 벡터를 제외한 후보 예측 움직임 벡터들 중 율-왜곡 관점에서 최적의 예측 움직임 벡터를 선택하고 그에 대한 인덱스 정보에 대해 모순 검증 기술을 적용한다. 이를 통하여 후보 예측 움직임 벡터 대상들 중 모순으로 판명된 일부를 대상 후보 집합에서 제외시켜 부호화 효율을 증가시키는 방법을 제안한다. 제안하는 모순 검증 기반 움직임 벡터 부호화 방법은 H.264/AVC 방법과 비교하여 최대 1.8%의 비트량을 절감시킨다.
