摘要：

A nonparametric and unsupervised method of automatic threshold selection for picture segmentation is presented. An otpimal threshold is selected by the discriminant criterion, namely, so as the maximize the separability of the resultant classes in gray levels. The procedure is very simple, utilizing only the zeroth- and first-order cumulative moments of the gray-level histogram. It is strightforward to extend the method to multithreshold problems. Several experimental results are also presented to support the validity of the method.
