void vpMbtMeLine::display ( const vpImage< unsigned char > &  ,
vpColor   
)
inlinevirtual

Implements vpMeTracker.

Definition at line 80 of file vpMbtMeLine.h.

Referenced by vpMbtDistanceLine::displayMovingEdges(), and vpMbtDistanceCylinder::displayMovingEdges().

void vpMbtMeLine::display ( const vpImage< unsigned char > &  I)
inlinevirtual

Display the moving edge sites with a color corresponding to their state.

  • If green : The vpMeSite is a good point.
  • If blue : The point is removed because of the vpMeSite tracking phase (constrast problem).
  • If purple : The point is removed because of the vpMeSite tracking phase (threshold problem).
  • If red : The point is removed because of the robust method in the virtual visual servoing (M-Estimator problem).
  • If cyan : The point is removed because it's too close to another.
  • Yellow otherwise
Parameters
I: The image.

Reimplemented from vpMeTracker.
