title: Medical image processing feature descriptors
body: <p>I'm looking for local and global descriptors for medical image processing. I know about SIFT/SURF/GLOH/HOG, that are mainly applied to computer vision problems, but I would like to know if they are also applied to medical images to describe features or if there are specific descriptors in this field.</p>
  
  <p>I would really appreciate any hint.</p>
  
  <p>Thanks in advance,</p>
  
  <p>Federico</p>
