出了一种通过非线性逼近来控制最佳Bandelet化过程的方法。同时采用了沿几何流的方向小渡变换方法,直接把JPEG2000的编
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.

Jesse和Eric可以教你如何使用当前的 Ant,他们做得相当棒。这本书提供了颇有深度的信息,对于一些以往从未考虑到的工作,书中还介绍了如何扩展Ant来完成这些工作的详细内容。不论你是偶尔使用Ant,还是需要管理各种大型工程,这都是一本需要持之在手的工具书。”-Jesse and Eric can teach you how to use the current Ant, they did a very wand. This book provides a great depth of information, for some previous work has never been taken into account, the book also describes how to extend Ant to complete these work details. Whether you are occasionally using Ant, or the need to manage a variety of large-scale projects, this is a need to hold the tool in hand.
