void arGetImgFeature	(	int *	num,
		int **	area,
		int **	clip,
		double **	pos
	)

XXXBK.

XXXBK

Parameters:

	num	XXXBK
	area	XXXBK
	clip	XXXBK
	pos	XXXBK

ARInt16* arLabeling	(	ARUint8 *	image,
		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.
