摘　　要：离散小波变换是图像处理和压缩技术的基础,而基于提升方法的离散小波变换是当今业界研究的热点之一。在分析二维图像的小波变换的基础上,研究小波提升算法、其特点及其实施方法,探讨该算法在JPEG2000中可逆小波变换上的实现,给出该算法的C语言实现,并进行了分析。Discrete wavelet transforms become the basis of many technologies of image processing and compression. The DWT algorithm based on the lifting scheme is one of the most popular technologies in this domain. This paper analyzes 2D wavelet transforms of images, summarizes the lifting algorithm and its steps and merits and probes into application of this algorithm in the reversible transforms of JPEG2000.Finally, the realization and its analysis of the lifting wavelet algorithm in C language is given.
