Hi I have an immage 2048x2448 grayscale, I want to find all the pixel where the intensity is "255".

After i have find them i want to print this point on the immage

img; % 2048x2448 matrix
[r, c] = find(img==255); % r and c contain all row and columns

If you want to mark these points on the image

plot(c, r, '+')

It will draw '+' marker at those locations.

thx a lot!
