matlab code to filter the noise in a wav signal
-
Matlab.rar
This code is used with SRAD Filter. Which is used to remove speckle noise. This code is an addition to that as it auto windows the speckled area

Image_Filter.zip
SourceCode of Image Convolution.The type of filter is Mean, Median, or User defind. And the test of Median to reduce the noise of the salt and pepper.

SSR+TIWPT.zip
... for transient signals. Hypotheses:
Ho : x[n] = w[n] i.e. signal absent
H1 : x[n] = s[n] + w[n] i.e. signal present
NOTE :
received1 IS A CELL ARRAY corresponding to signal + noise.
received2 is a CELL ARRAY corresponding to the noise alone.

SNR_Gain_for_SSR.zip
Function to find SNR gain for a Suprathreshold Stochastic resonance detector and hence compute the optimal value of sigma, which is the optimal amount of noise to be added in order to obtain the highest SNR.

程序使用说明：
1、软件应用平台：Matlab6.5或更高；
2、打开方法：
将文件所在目录设为工作目录，然后打开wavlet.fig,在noise提示框下输入噪声强度，在0-0.1之间（不能为零）。
然后点process按钮，就会显示实验结果，包括原图像，加噪图像，去噪图像的对比以及当前的psnr值。
wavlet.m是程序文件。
程序内容写在在程序的注释里。
阈值的更改没有实现可视化，在源程序中可以改。
