The paper mentions computation of px as 'summing the rows' of cmat (GLCM matrix) i.e sum of values in x (horizontal) direction, which in python corresponds to summation along axis=1; and py as sum of column values or sum of values in y (vertical) direction, which in Python corresponds to summation along axis=0.
