Detailed Description

main structure for detected marker.

Store information after contour detection (in idea screen coordinate, after distorsion compensated).

Parameters:

area	number of pixels in the labeled region
id	marker identitied number
dir	Direction that tells about the rotation about the marker (possible values are 0, 1, 2 or 3). This parameter makes it possible to tell about the line order of the detected marker (so which line is the first one) and so find the first vertex. This is important to compute the transformation matrix in arGetTransMat().
cf	confidence value (probability to be a marker)
pos	center of marker (in ideal screen coordinates)
line	line equations for four side of the marker (in ideal screen coordinates)
vertex	edge points of the marker (in ideal screen coordinates)
