title: Histogram Equalization on image originally with logarithmic distribution
body: <p>I have an image array which, because of the physical nature of the acquisition process, has a log distribution. What is the standard workflow for Histogram Equalization (HE) in this scenario: 1\apply HE directly; or 2\ apply log10(x) transformation and then HE?</p>
  
  <p>Thanks!</p>
