Class NormalizationPoint2D


public class NormalizationPoint2D extends Object
Describes how to normalize a set of points such that they have zero mean and variance. This is equivalent to applying the matrix below. Normalization is often needed as a preprocessing step for solving linear equations. Greatly reduces bias and numerical errors.
 N = [ 1/σ_x     0      -μ_x/σ_x ]
     [    0   1/σ_y 0   -μ_y/σ_y ]
     [    0      0          1    ]
