Discret-Wavelet-Transform-got-Daub2-by-Santhana-R
y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level
It returns the matrix of all decompositions and the final approximations.
Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes.
For other wavelets, the filter values alone can be changed or WFILTERS can
be used.
The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author.
Example:
clear all
t=[0:0.0003:8*pi]
x=sin(5000*t)+sin(1000*t)
x=x(1:2^16)
level=5 Fs=1/0.003
d2wavelet(x,Fs,level)
Thanks for Downloading. Don t forget to rate or comment.

该代码是自己编制的,主要用于红外图像的特征提取,其中提取长宽比,复杂度,紧凑度,均值比,不变矩等七种红外图像的特征,可很好的为以后的识别做准备(The code is compiled their own, mainly for the infrared image feature extraction, which extract the aspect ratio, complexity, compactness, mean ratio of seven invariant moments and other characteristics of infrared images can be very good for the future identification prepare)

说明: 用matlab编的Capon算法和延迟相加法的程序,能够实现不同信号入射时的DOA估计,从而可以比较两种算法的分辨率等(Used for the Capon algorithm matlab and delays add up to the law of procedure, to achieve different signal DOA estimates at the time of the incident, which can compare the two algorithms, such as the resolution)

CoSaMP-and-OMP-for-sparse-recovery
压缩感知信号恢复算法OMP和CoSaMP算法,常用的算法( x = CoSaMP( A, b, k )
uses the Compressive Sampling Matched Pursuit (CoSaMP) algorithm
(see Needell and Tropp s 2008 paper http://arxiv.org/abs/0803.2392 )
to estimate the solution to the equation
b = A*x (or b = A*x+ noise )
where there is prior information that x is sparse.z)
