Member Function Documentation

virtual void vpMeTracker::display	(	const vpImage< unsigned char > &	I,
		vpColor	col
	)

pure virtual

Implemented in vpMeNurbs, vpMeLine, and vpMeEllipse.

Referenced by vpMeLine::computeRhoSignFromIntensity(), display(), vpMeNurbs::getNurbs(), vpMeEllipse::initTracking(), vpMeLine::track(), and vpMeEllipse::track().

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

virtual

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.

static

Test whether the pixel is inside the mask. Mask values that are set to true are considered in the tracking.

Parameters

mask	Mask image or NULL if not wanted. Mask values that are set to true are considered in the tracking. To disable a pixel, set false.
i	: Pixel coordinate along the rows.
j	: Pixel coordinate along the columns.
