摘　　要：研究一类非线性微分变换算子及其离散格式 ,它们在信号和图象处理中可视为一种非线性滤波器 。Some nonlinear differential operators and their discrete schemes are considered. The discrete schemes can be used as nonlinear filters in the field of Signal and Image Processing. They possess some interesting features while the linear filters do not. [
