title: Get most clear iplimage from the buffer
body: <p>How can I get most clear iplimage among rest , using OpenCV.? When there is no training image to compare.</p>
  
  <p>As a example there is a web cam input which move a hand. But when I stream this video ,I get 10 iplimages. But only 5th one is more clear. I want to filter that 5th one using openCV.</p>
  
  <p>Its good to evaluate each and every iplimage (10 images) and assign rank using clearness of the images. Is there any way to do it so..?</p>
  
  <p>I hope kindness support from your all.</p>
  
  <p>Thank you.</p>
