Dear What I understand is you will randomly swap the pixel values of images 6 times. At the end you will have 6 images. Again multiple ways to do it. Here is one example.
myface = imread('myface.jpg'); % this is your image
myface1 = myface; % just to keep the copy of original
for i=1:6 % this decides how many times you want to repeat
myRan = randperm(prod(size(myface))); % we assume myface.jpg is grayscale
myRan=reshape(myRan,size(myface));
myface(myRan) = myface;
myimageset{i} = myface;
myface = myface1;
end
Now you have six images in myimageset. You can get image by myimageset like this.
image1 = myimageset{1};
you can put myimageset in loop and display each image to see your output. The code I have written is not optimal. The computation speed can be improved. I did this way to divide the process into step so that you can follow what actually is happening.
