MATLAB: Error in imabsdiff of two images

You are trying to take the image difference between file names. You need to read in the files and compare the contents.

MATLAB: Do I obtain only ones when I use STRETCHLIM function on an image in the Image Processing Toolbox 5.3 (R2006b)

This occurs when the image is not normalized. In order to have STRETCHLIM work, normalize the input image as shown in the following example:

load img
img2 = img/max(img(:));
LOW_HIGH = stretchlim(img2);
img3 = imadjust(img2,LOW_HIGH);
figure(1); clf;
subplot(211)
imshow(img2)
subplot(212)
xlabel('Adjusted image')
imshow(img3)
