capture crashes with matches parameter about capture HOT 3 CLOSED

Ok apparently lena.jpg is assumed to be the image the orb_template produces among all the feature files. Could ve been written down somewhere ;) But why is this image not stored in the same directory as the .yaml files? And why are you looking for lena.jpg? And why is that hard codet?

edit: the lena.jpg thing was fixed, the template image now is stored in the right directory as train.png. But the issue with the capture doing nothing along with the constantly black mask image remains ...

from capture.

the lena.jpg issue is a default parameter in ecto_opencv. The template was not saved properly in the folder. That got fixed in trunk. I am checking you other two errors.

Thx for reporting the bug: I was able to reproduce it and fixed it in ecto_opencv 0.4.22. You can just add it to your workspace or wait for the package to be built.
The mask just displays the mask of the object, I'll just add some info in the new docs. If you display the matches, and if you do get matches, the mask should not be empty.
