解码器应用到Bandelets变换系数上进行有效的图像压缩，而无需重新构造上下文模型。实验表明，提出的压缩方法具有很好的边
缘和纹理保护能力，特别对于直线纹理图像，压缩性能优于JPEG2000标准。-Abstract：Image compression based on the second generadon Bandelets transform，whose optimized bandeletization is controlled
by quantization step，cannot realize fixed bitrate image compression．To overconae this problem。the paper presents a non-linear
approximation method to control the optimized bandeletization．Then，the oriented wavelet transform along geometric flow is adopted．
The JPEG2000 codec is direcdy employed on bandelets coefficients to implement effective image compression without changing
context model．Experiments show that the proposed compression method exceeds JPEG2000 standard in compression performance
and abil畸of image edges and texture preservation．
