Abstract

In this paper, a new improved EREC based error resilient coding in JPEG-2000 standard is proposed, considering the error sensitive wireless environment with limited channel capacity. In order to apply EREC, we use the variable bit-rate by using R-D optimization. Simulation results demonstrate that the proposed EREC based error resilient coding is more resilient than the error resilient schemes used in JPEG-2000.

본 논문에서는 채널용량이 제한되고 에러에 민감한 무선환경을 고려하여 압축율이 기존의 방식보다 크고, 에러에 강인한 JPEG-2000 압축 표준을 기반으로 하여 새로운 EREC 기법을 적용한 에러강인 부호화를 제안하였다. JPEG-2000의 웨이브렛 변환 기반 내장형부호화기법(EBCOT)이 가지고 있는 슬롯 당 고정 비트율은, 율왜곡(R-D) 최적화에 의하여 가변 비트율로 변환하였고 여기에 EREC 기법을 적용하였다. 모의실험은 제안된 방법이 기존의 채널 코딩과 블록 경계 표시 헤드를 이용한 기존방법보다 특히 낮은 비트율에서 더욱 좋은 에러보정 능력을 보이는 것을 검증하였다.
