| Abstract: | Provides a O-th order cumulative moment discriminant optimal threshold selection method.In the sense of least squares,this method just only deals with O-th order cumulative moment for evaluating the goodness of threshold.This method not only reduces the order of discriminant cumulative moment to the lowest order in the thoery,but also decreases the quantity of calculation. |

| Keywords: | O-th order moment least sequence threshold cumulative moment |
