Abstract

Based on the fact that high similarities exist between viewpoints of multi-view images, MV-HEVC achieves high encoding efficiency by performing conventional temporal direction prediction in a single viewpoint as well as inter-view prediction between viewpoints. In this paper, we propose to integrate SHVC and MVC (Multi-view Video Coding) to implement scalable multi-view video encoder using HEVC as a base layer. According to experimental results, it is verified that the BD-PSNR improvement reaches up to 1.5dB while reducing the BD-Bitrate by around 50~60%.

다시점 이미지의 뷰포인트 간에 높은 유사도가 존재함을 바탕으로 MV-HEVC는 뷰포인트 내에서 전통적인 시간적 방향 예측 뿐만 아니라 뷰포인트 간에 예측을 수행함으로써 높은 부호화 효율을 얻는다. 본 논문에서는 HEVC를 기본 계층으로 사용하는 스케일러블다시점 비디오 부호화를 구현하기 위해 SHVC와 MVC를 통합 구현함을 제안한다. 실험결과에 의해 BD-PSNR 개선이 1.5dB에 이르고 동시에 BD-Bitrate를 50~60% 가량 줄일 수 있음을 확인하였다.
