Detailed Description

Class that defines what is a feature generic tracker.

A tracker is able to track features with parameters expressed in:

  • in the camera frame cP. These parameters are located in the public attribute vpTracker::cP.
  • in the image plane p. These parameters are located in the public attribute vpTracker::p. They correspond to normalized coordinates of the feature expressed in meters.
