Abstract: 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.

Key words: nonlinear filter, signal and image processing, upwind, downwi
