这是一个matlab的源码。代码实现了图像的level set 分割方法(This is a matlab source. Code to achieve the level set image segmentation method)

Adopt mean value wave filtering way to dislodge noise to the image(Adopt mean value wave filtering way to disl odge noise to the image)

The brief idea of the algorithm is that every image s pixel is set to black if its brightness is T percent lower than the average brightness of the surrounding pixels in the window of the specified size

Creating the training and testing sets

使用matlab常用绘图命令说明。。。。。(Matlab drawing commands using common instructions)

1.计算梁的刚度矩阵 2.高斯积分 3.T3单元的刚度矩阵(1. Calculate the beam stiffness matrix 2. Gaussian integral 3.T3 element stiffness matrix )

清华大学张旭东老师《现代信号处理》课第二次大作业代码。高效正确地实现RLS算法。(This is an efficient and correct implementation of the RLS algorithm .This code is especially for the project of modern signal processing ,which is tought by Zhang Xudong in Tsinghua University.)

emd经验模式分解算法，特别适用于非线性非平稳信号的分析处理(Empirical Mode Decomposition)

说明：  基于原子分解的调频信号参数识别算法估计性能得到了很到的提高(paramater estimation of modulated signal based atomic decomposition)

WAVEVIB generates a vibroseis waveform (Clauder wavelet) by ％ first calling SWEEP to generate a linear sweep and then calling ％ AUTO to autocorrelate that sweep. Theoretically, the autocorrelation ％ length is ~ 2*slength but only only the central wlength long ％ part is generated. This is like windowing the auto with a boxcar.(WAVEVIB generates a vibroseis waveform (Clauder wavelet) by first calling SWEEP to generate a linear sweep and then calling AUTO to autocorrelate that sweep.
