noise (0 to 60 in multiples of 4)
minimal required length of monotonous region to be reliable; higher
values result in higher reliability of EDDI, but less steep edges will be
detected (2, 3, 4 or 5)
lower values increase the amount of compensation (1 to 16)
limitation of the compensation factor of EDDI; 1 limits to full EDDI
compensation, 16 limits to almost no EDDI compensation (1 to 16)
