def laser_camera_segmentation.gaussian_curvature.gaussian_curvature	(		points,
			p = np.matrix([0,0,
			T
	)

Fits a plane.

Parameters:

points	3xn numpy matrix representing points to be fitted
d	direction that normal calculated should point in

Returns:

normal and eigen value points (in descending order)

Definition at line 38 of file gaussian_curvature.py.

def laser_camera_segmentation.gaussian_curvature.gaussian_curvature2	(		points,
			x = np.matrix([1,0,
			T,
			z = np.matrix([0,0,
			T
	)

Calculates a coordinate system & eigen values of given points matrix.

Parameters:

points	3xn numpy matrix representing points to be fitted
x	first principle direction to match to
z	second direction to match to

Returns:

(3x3 matrix describe coordinate frame, list with associated eigen values)
