Hello,
For image separation concave hull algorithm is necessary, because not all objects are convex.
I am searching a delphi translation of a Concave hull algorithm. It was developed by a portuguese institute here in Mathematica.
http://repositorium.sdum.uminho.pt/bitstream/1822/6429/1/ConcaveHull_ACM_MYS.pdf
Later it was translated into C#.
Has anybody made a translation to delphi? For ImageEn it would be very helpful for image analysis.
Sincerely
Peter |

Hi Peter,
i noticed you question also in the embarcadero forum.
I am having the exact same problem. I can not find a delphi/pascal implementation of the concave hull algorithm.
Did you ever find one?
Regards,
Manuel |

Hello,
I found now an implementation of the concave hull in c++.
https://www.codeproject.com/Articles/1201438/The-Concave-Hull-of-a-Set-of-Points
It uses also the Flann library.
Has anybody installed it in Embarcadero C++Builder?
Sincerely Peter

Hello,
I found the most recent implementation http://andriiheonia.github.io/hull/.
It is written in javascript.
So my question still is: Has anybody translated it to delphi?
I would also pay for a translation. There are only in total 358 lines of source code.
Sincerely
Peter |
