		double **	pos
	)

XXXBK.

Parameters:

num	XXXBK
area	XXXBK
clip	XXXBK
pos	XXXBK

		int	thresh,
		int *	label_num,
		int **	area,
		double **	pos,
		int **	clip,
		int **	label_ref
	)

extract connected components from image.

Label the input image, i.e. extract connected components from the input video image.

Parameters:

image	input image, as returned by arVideoGetImage()
thresh	lighting threshold
label_num	Ouput- number of detected components
area	On return, if label_num > 0, points to an array of ints, one for each detected component.
pos	On return, if label_num > 0, points to an array of doubles, one for each detected component.
clip	On return, if label_num > 0, points to an array of ints, one for each detected component.
label_ref	On return, if label_num > 0, points to an array of ints, one for each detected component.

Returns:

returns a pointer to the labeled output image, ready for passing onto the next stage of processing.

void arLabelingCleanup

(

void

)

clean up static data allocated by arLabeling.

In debug mode, arLabeling may allocate and use static storage. This function deallocates this storage.
