Abstract

In this paper, we propose adaptive near-lossless image coding algorithm according to bandwidth while maintaining image quality. The proposed method adjusts error range using amounts of encoded bits and target bits at a slice encoding interval. Experimental results show that our proposed method not only almost fits compression into bandwidth, but also has better image quality.

본 논문에서는 전송 대역폭에 따라 손실을 최소화하며 적응적으로 압축률을 조절하는 준무손실 영상 부호화 알고리즘을 제안한다. 제안하는 방법은 슬라이스 부호화 간격으로 부호화된 비트량과 목표 부호화 비트량을 이용하여 적응적으로 허용 오류 범위를 변경한다. 실험 결과, 제안하는 방법은 기존 알고리즘들에 비하여 효과적으로 전송 대역폭에 맞추어 압축률을 조절할 뿐만 아니라 화질 또한 향상됨을 알 수 있다.
