Abstract

In this paper, we introduce a new scanning method for MPEG-4 AVC based Fine Granular Scalable video coding that can significantly improve the subjective picture quality of a decoded scalable video. The proposed scanning method can guarantee the subjectively improved picture qualify of the decoded scalable video by encoding, transmitting and decoding the visually important region most-preferentially. From the simulation results, it has been found that the proposed scanning method can lead the FGS method to achieve significantly improved picture quality, especially on the region of interests.

본 논문에서는 MPEG-4 AVC (Advanced Video Coding) 기반 미세입자 스케일러블 (Fine granular scalable: FGS) 비디오 코딩 기법의 성능을 향상시킬 수 있는 새로운 스캔 방법을 제안한다. 제안한 방법에서는 전송하고자 하는 영상에서 시청자에게 시각적으로 중요한 부분을 우선적으로 부호화하여 전송하고, 수신단에서도 해당 영상 정보를 우선적으로 복호화함으로써, 복원된 스케일러블 비디오의 화질을 향상시킨다. 제안한 방법의 성능을 확인하기 위한 실험 결과로부터 제안한 방법을 FGS에 적용하는 경우에는 복원 영상의 주관적인 화질을 크게 향상시킬 수 있음을 확인하였다.
