Re: Generating a random matrix through a natural image

Hi All,

I want to create a random valued matrix from a natural image matrix.
For example, if we take the lena image 256x256, the pixel values in
the matrix 256x256 should be arranged in such a way that the values
are not related to each other. Basically, I should have the same
histogram from the two matrices, but I want to remove dependencies
between pixels in a natural image.  I used the algintrlv method in
matlab,

image_file = imread('E:\TestData\lena.jpg');
im1 = algintrlv(image_file,128,'takeshita-costello',125,126);


try

im1 = zeros(size(image_file));
im1(:) = randperm(image_file(:));
