摘要 JPEG2000标准的核心算法是EBCOT,它不仅能实现对图像的有效压缩,同时产生的码流具有分辨率可伸缩性、信噪比可伸缩性、随机访问和处理等非常好的特性。本文介绍了E BCOT编码算法的主要过程。 EBCOT is core algorithm in JPEG2000 standard,which can compress image efficiently,and the bit-stream have the excellent characteristics: multi-resolution retractility, signal-to-noise retractility, random access and process. This paper describes main procedures of EBCOT algorithm.
