Detailed Description

internal structure use for marker detection.

Store information after contour detection (in observed screen coordinate, before distorsion correction).

Parameters:

	area	number of pixels in the labeled region
	pos	position of the center of the marker (in observed screen coordinates)
	coord_num	numer of pixels in the contour.
	x_coord	x coordinate of the pixels of contours (size limited by AR_CHAIN_MAX).
	y_coord	y coordinate of the pixels of contours (size limited by AR_CHAIN_MAX).
	vertex	position of the vertices of the marker. (in observed screen coordinates) rem:the first vertex is stored again as the 5th entry in the array – for convenience of drawing a line-strip easier.
