摘　　要：JPEG2000编码标准以多分辨率小波变换为基础,其编码参数的取值对图像压缩的性能和质量有重要的影响。在分析小波变换的多分辨率特性与提升方案的基础上,实验研究其多分辨率小波变换参数的选取对编码性能和图像质量的影响,提出不同的压缩比下主要编码参数的适宜取值范围,得到适合的图像。Multi--resolution wavelet transform is the base of JPEG2000 coding standard, the value of the encoding parameters of the image compression performance and quality has important implications. Based on the analysis of multi--resolution wavelet transform and enhance the characteristics of the program,on the basis of the experimental study of its multi-- resolution wavelet transform coding parameters on the performance and image quality are affected by the compression ratio , under different encoding parameters of the main values of the appropriate the scope to be suitable for the image.
