I have some pixels with value more than 1 , I want to find randomly from those pixels. I tried this command : randi(size(imfinal),1,5) but it gives me random number of pixel number. I want exactly the number of i , j of the pixel,and those pixel which their value is more than 1 .
How can I find random pixels in an image?

Hi all, I have a 256*256 pixels image and I want to have 5 randomly pixels in it.how can I do that?

That does not do what you asked. The first loop merely assigns the entire image to f. The second part looks at only the first 1800 pixels with a value of more than 20 and picks the linear index of 5 of them.
It doesn't give you "number of i , j of the pixel" and doesn't look at "those pixel which their value is more than 1". But whatever...as long as you're happy.
