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。

至于效果，见仁见智，有效果的大家都知道了，还有很多，估计连水泡都没有冒一个。

BMEICS synthesizes the character of block motion estimation and that of global search, diversity, and no prone to premature in immune clonal selection.

仿真实验结果表明，在大多数序列上，该算法都比已有的快速搜索算法具有更高的性能和更少的平均搜索点数。

Tridiagonal block matrix elemination and sweep algorithm is successfully applied to solve the large matrix involved; central difference method is supplemented to Houbolt method to form a time integration method with estimation and correction, to solve the time integration of second order implicit non-linear equation; simplification of system equation by decoupling between the physical coordinates x and y further improves the calculation accuracy and speed.

其中：成功地引入块三对角矩阵追赶法求解上述问题构成的大型矩阵；提出中心差分法+Houbolt法的预估计—校正时间积分法，以解决二阶隐式非线性方程的时间积分问题；系统方程在物理坐标x和y上的"解耦"简化，使计算速度和计算精度得以进一步的提高。
