| Nov 3, 2014 at 21:08 | comment | added | Vidit Nanda | @IgorRivin How does image segmentation and/or persistence identify the boundary in any sense of a planar point set? One might get a one-parameter family of partitions of these points, but it isn't clear how that would help with the problem at hand. | |
| Nov 3, 2014 at 17:55 | comment | added | Igor Rivin | This is as good an application of persistent homology as there ever was, and "image segmentation" might be the most appropriate part of EH. | |
| Nov 3, 2014 at 17:52 | comment | added | Vidit Nanda | I'm not sure how anything in EH answers the question (I have the book in front of me). Did you have any specific part of the book in mind? | |
