About VPtree

[Dorothy-2016]

Hi Zach,rencently I am study this interesting thing that you have completed,now i have some trouble to understand its principles,in https://developers.google.com/web/showcase/2016/land-lines you say it use Structured Forest edge detection in opencv to detect lines,and ridge detection in ImageJ to get the lines and identify individual lines from each other,now I read this javascript code ,i have a question that what the VPtree do? Does it means the method of Structured Forest edge detection?
