◆ initClick()

void vpTemplateTracker::initClick	(	const vpImage< unsigned char > &	I,
		bool	delaunay = `false`
	)

Select the reference template in image I using mouse click.

Parameters

I Image containing the reference template.

delaunay

Flag used to enable Delaunay triangulation.

If true, from the image points selected by the user, a Delaunay triangulation is performed to initialize the reference template.
- A left click select a image point;
- A right click select the last image point and ends the initialisation stage.
If false, the user select directly points as successive triangle corners. The size of v_ip vector should be a multiple of 3. It is not mandatory that triangles have one edge in common; they can define a discontinued area.
- A left click select a triangle corner;
- A right click select the last triangle corner and ends the initialisation stage. For example, to select the reference template as two triangles, the user has to left click five times and finish the selection on the sixth corner with a right click.

Initialize the reference template from a vector of points.

Parameters
