Image despeckling using a non parametric statistical model of wavelet coefficients in matlab

The following Matlab project contains the source code and Matlab examples used for image despeckling using a non parametric statistical model of wavelet coefficients. This is a demo program of the paper J. Tian and L. Chen, "Image despeckling using a non-parametric statistical model of wavelet coefficients," Biomedical Signal Processing and Control, Vol. 6, No. 4, Oct. 2011, pp. 432-437.

Miscellaneous tools for image processing in matlab

The following Matlab project contains the source code and Matlab examples used for miscellaneous tools for image processing. eachchannel  allows us to apply function for each channel imgrad  calculates horizontal and vertical gradients impsnr  evaluates the psnr and the rmse beween images imreadind  reads image file from file even if the image file is index color, imreadind can read image data as well as rgb image data   rgb2ycc  transfers color space from rgb to ycc ycc2rgb  transfers color space from ycc to rgb .

Psnr for rgb images in matlab

The following Matlab project contains the source code and Matlab examples used for psnr for rgb images. The function, PSNR_RGB( X,Y) computes the PSNR for two RGB images using the formula :                      MSE(X,Y)=SUM(1,n)SUM(1,m)SUM(1,p) [X(i,j,k)-Y(i,j,k)]²                      d= max(max(X),max(Y))| PSNR(X,Y)=10.
