Finite_element_tri

该程序的主要功能是对心音信号进行AR功率谱分析，同时带有去噪功能。(The program' s main function is to heart sound signals AR power spectrum analysis, and with denoising function.)

用ＭＡＴＬＡＢ实现ＬＭ算法库，使用时添加其为工作目录，便可使用各种函数．(LM algorithm using MATLAB realize the Treasury, when used to add its working directory, you can use a variety of functions.)

Hi This is very simple zoom and shrink image program for 256 x 256 size image

Skin Tone Data Hiding Technique

信号1维和2维周期性双正交基的小波分析，主要是用作滤波方面，可构造非对称滤波器。(Wavelet analysis signal a 2-dimensional and two-dimensional periodic orthogonal basis, mainly used for filtering, the filter can be constructed asymmetric.)

说明：  可以实现2ask的调制，在信噪比SNR为0，10，20。如有需要者可下载。(it is a good matlab program! it can produce a 2ask signal at SNR=0,10,20.)

说明：  基于Graph Cut的一种分割方法，比较著名的论文。(Graph Cut based on a segmentation method to compare the famous paper.)

The program uses a simple algorithm to calculate the deflection at each point of a cantilever beam subjected to arbitrary loading distribution, the program also calculates and plots the bending moment and shear force in the beam.
