title: How to access a points in CvSeq in javacv?
body: <p>I'm developing project using javacv and I was able to identify polygon and I store that details in CvSeq. I try to access the points in that structure but it doesn't work for me. So please can some one explain how to access points in CvSeq structure in javacv?</p>
  
  <p>For example I need to access the 8 edge points of following image. So i could be able to access the lengths of each side of the polygon.</p>
