bool ProjectiveBasis2D::collinear ( ) const [inline]

Were three of the four given basis points collinear ?.

	)		`[protected]`

Find the transformation which maps the 4 points to the canonical projective frame using the linear method of [Beardsley et.

al., ECCV96]. If three of the four points are nearly collinear, an error message is printed, but the computation is still carried out.

Return the planar homography that maps the points to the canonical frame.
