title: Increasing Image Contrast in MATLAB
body: <p>I have a greyscale image which has pixel values ranging from 1.000 to 1.003.</p>
  
  <p>I would like to increase the contrast between the different pixels. I have tried <code>imcontrast</code> under <code>imtool</code>, but I'm not seeing any improvement visually.</p>
  
  <p>Perhaps an idea would be to increase values of pixels >1.000. For example, it would be great if I could map 1.001 to 10, 1.002 to 20 etc. Would that increase contrast?</p>
