Speech Enhancement A Bayesian Estimation Approach Using Gaussian Mixture Model

SQP matlab优化源程序SQP方法(SQP method)

The sparsity of signals and images in a certain trans-form domain or dictionary has been exploited in many applications in signal and image processing. Analytical sparsifying transforms such as Wavelets and DCT have been widely used in compression standards. Recently, synthesis sparsifying dictionaries that are di-rectly adapted to the data have become popular especially in appli-cations such as image denoising, inpainting, and medical image re-construction.

本程序用来计算空心铜绕线圈（磁体）在液氮温度下的电阻，需要线圈结构，尺寸，导线截面等数据(This procedure is used to calculate the hollow copper winding coils (magnets) at liquid nitrogen temperature resistance, the coil structure, size, conductor cross-section and other data)

matlab图像处理实例详解第三章源码程序，推荐大家一起学习，很好很实用。(Detailed examples matlab image processing Chapter III source program, recommend everyone to learn, very very useful.)

说明：  简单的遗传算法求最大值的例子，只需按说明修改目标函数即可(Simple example of the maximum genetic algorithms)

用MATLAB编写的混沌序列图像加密程序，密钥可以从0到1之间的任何一个数，加密密钥跟解密密钥一样才能正确解密。(MATLAB prepared by the chaotic sequence image encryption procedures, Key from 0-1 between any one of the few, encryption, decryption keys with the same key can decrypt correctly.)

功能描述： 小数延迟FIR滤波器，对参考阵元信号signal_ref进行 length(tau) M次延迟，分别得到M个阵元的采样信号 关键问题： 若τ 1.2Ts,则Delay(i) 2,tau_valid(i) 0.2Ts 若τ 0.6Ts,则Delay(i) 1，tau_valid(i) -0.4Ts 当tau_valid(i)>0或<0时，从卷积后的数据y_FIR_delay中取值启示位置不同 函数能够实现输入任意延时tau，输出信号波形与理想波形之间误差很小。( Description: fractional delay FIR filter array element of a reference signal signal_ref performed length (tau) M delay times, respectively, to obtain a sample signal array element M key question: if τ 1.2Ts, then Delay (i ) 2, tau_valid (i) 0.2Ts if τ 0.6Ts, then Delay (i) 1, tau_valid (i) - 0.4Ts when tau_valid (i)> 0 or < 0, the volume data y_FIR_delay product after the Enlightenment values at different positions function can be realized enter any delay error between tau, the output signal waveform and the ideal waveform is small.)

直方图均衡化的另一种解法，不是用累加的方法得到的，是用分配灰度值空间的办法。(Histogram equalization another solution, instead of using the cumulative method is the use of the distribution of gray value space approach.)
