JPEG2000是新一代静态图像压缩标准，它具有优良的压缩性能和很高的灵活性。介绍了JPEG2000的编码流程，研究了它的核心算法，重点分析了JPEG2000所采用的提升小波变换。并得出JPEG2000与传统的图像压缩标准相比确实具有更加优越的性能的结论.-JPEG2000 is the next generation still image compression standard, it has excellent compression performance and high flexibility. Introduced the JPEG2000 encoding process, to study its core algorithms, the focus of analysis used by the JPEG2000 lifting wavelet transform. And came to the JPEG2000 image compression with the traditional standards we do have a more superior performance conclusions.
