openalea.eartrack.eartrack.robust_majors_axes_regression_ww(pixels)

Performs a robust major axis regression on 2D distributed dots

Robustness come from ‘hinich et al.’ algorithm :param pixels: (np array of 2 np array of int) distributed dots to perform regression :return: a: (float) slope of robust regression line

b: (float) intercept of robust regression line useful_pixels: (np array of 2 np array of int) dots kept by robust

regression

useless_pixels: (np array of 2 np array of int) dots ousted by

robust regression
