Constructor & Destructor Documentation

TrackingWindow::TrackingWindow	(	int	window_id,
		int	theta_start,
		int	theta_end,
		int	theta_max,
		int	freeze_frame_bound
	)

Parameters:

	window_id	Window id to differentiate between the other "windows" tracked.
	theta_start	Start angle
	theta_end	End angle.
	theta_max	Upper bound of theta.
	freeze_frame_bound	Number of frames the window keeps being tracked. If it's a false-positive it will be removed after freeze_frame_bound frames.

Returns:

Window id.

bool TrackingWindow::update_window_bounds	(	int	new_theta_start,
		int	new_theta_end
	)

Parameters:

	new_theta_start	New theta start
	new_theta_end	New theta end

Returns:

false if the freeze status has expired

void TrackingWindow::write_window_to_table

(

char *

degree_table

)

Usually this func is called after OmniTracking::test_tracking_window_availability which tests the availability of free space in the table itself.

Parameters:

degree_table

Degree Table. The effective array of chars which takes take of writing the symbols is proprietary of OmniTrackingTable class.

Note:

No check is done on value of the destination cell.
