You're passing a 2-by-3 matrix into imadjust as its second input argument. According to that documentation page this is valid if the input is an "RGB image or colormap". From the fact that you receive an error I'm guessing your data is actually a "Grayscale image". But I can't see a definition for app.Modified so I can't be certain.
