imagingbook.common.geometry.fitting.line.OrthogonalLineFitHomogeneous
All Implemented Interfaces:
LineFit
public class OrthogonalLineFitHomogeneous extends Object implements LineFit

This class implements line fitting by orthogonal regression to a set of 2D points by solving a homogeneous linear system. See Sec. 6.7.1 of [1] and Sec. 10.2.2 (Alg. 10.2) of [2] for additional details.
