By use of bipartition, the entropy of each wavelet block approximates to the target bit rate of one. 5. An efficient algorithm is presented for constructing quantization tables of wavelet blocks with optimal bit allocations for a given image. The algorithm uses wavelet coefficient distribution statistics in a novel way, and pays attention to the traits of HVS.

该算法首先根据每个小波块所含能量的多少和到每个小波块实际编码所用的比特数，给其分配不同的码率；然后根据二分法，通过调整各小波块的量化因子使得各小波块的熵逼近它的目标比特率。

The statistics of the contourlet coefficients of natural images in detail and model contourlet coefficients using non-Gaussian bivariate distribution that captures their interscale dependencies are studied.

详细分析了图像contourlet系数的统计特性，并利用非高斯双变量分布对系数层间相关性进行建模。

To improve the performance of image-denoising methods, a locally adaptive denoising algorithm was presented. The new algorithm assumed the statistical dependence among wavelet coefficients. First, a bivariate probability distribution model was introduced to model the statistics of wavelet coefficients, and corresponding nonlinear threshold function was derived from the model using the Bayesian estimation theory.

由于图像小波系数存在很大的层间相关性，引入双变量概率分布模型，基于贝叶斯估计理论，得到了相应的非线性阈值函数；基于层内局域方差估计，利用该收缩函数得到一种局域自适应的图像去噪算法。
