[Insight-users] Kd-tree implementation in ITK is buggy and unreliable

[Ali -]

Hi,

A quick search in the mailing list shows that, during the past half a decade, it has been reported many times that the kd-tree classes in ITK are buggy. Writing some library based on ITK, it took me a few days to find out that the bug in my library is actually introduced by the kd-tree implementation in ITK which FINDS THE WRONG NEAREST NEIGHBOUR.

I have no idea, against many warnings from the users, why the bug has not been resolved yet. In the case it is difficult to address the bug, one option is to wrap many other existing implementations, personally I switched to libkdtree++.
