问题
I am looking for an OpenCV implementation of a function to find the concave hull of a set of points (as for the convexHull function). Does anyone know of it?
Here is an explanation: http://ubicomp.algoritmi.uminho.pt/local/concavehull.html
Thank you in advance.

You can also use Growing Neural Gas algorithm.
There are several implementations in web take a look at ( https://github.com/BelBES/libGNG ) for example.
Video of the algorithm is here: http://www.youtube.com/watch?v=fVd4ly8wilY
Very interesting java applet here:
Also take a look at this site: http://www.demogng.de/
