I installed the vlfeat library using apt-get install octave-vlfeat. For some reason, the SIFT function does not work, and says "vl_sift() undefined". This is at the same time when functions like vl_hog() and vl_kmeans() do work perfectly fine.

No results for which vl_sift.

Has anyone else faced similar issues? Is there some additional dependency?

Octave 3.8.1

  • Have you run vl_setup before? – Andy May 08 '15 at 13:00
  • @Andy no, `vl_setup` is undefined too. And yet I was able to use the functions I mentioned. – a-Jays May 09 '15 at 06:47
  • Did you load it with "pkg load vlfeat"? Does "pkg list" show an * after your package? – Andy May 11 '15 at 08:30
  • `pkg load vlfeat` says it is not installed, and it doesn't show up in `pkg list` at all. Although, trying to install it via `apt-get install` tells me it's already the newest version. What am I missing here!? – a-Jays May 11 '15 at 11:44
