Detailed Description
A ttrack is a set of tkeypoints showing the same physical point on successive frames.Definition at line 140 of file tracks.h.
Constructor & Destructor Documentation
| ttrack::ttrack | ( | tracks * | db | ) | [inline] |
Definition at line 157 of file tracks.h.
References keypoints, and length.
Referenced by ttrack::factory_t::create().
Member Function Documentation
| virtual void ttrack::point_added | ( | tkeypoint * | ) | [inline, virtual] |
An overloadable method that is called whenever a point is added to the track.
The inserted point is assumed to be yet unmatched, i.e. it does not belong to another track.
Reimplemented in pyr_track.
Definition at line 163 of file tracks.h.
References length.
Referenced by tracks::set_match().
| virtual void ttrack::point_removed | ( | tkeypoint * | ) | [inline, virtual] |
An overloadable method that is called whenever a point is removed from the track.
Reimplemented in pyr_track.
Definition at line 166 of file tracks.h.
References length.

pointer to the latest point of the track, i.e.
on the latest frame the point has been seen. keypoints->matches.next is always null.
