Nonlinear Digital Filters: Principles and Applications

The function of a filter is to transform a signal into another one more suitable for a given purpose. As such, filters find applications in telecommunications, radar, sonar, remote sensing, geophysical signal processing, image processing, and computer vision. Numerous authors have considered deterministic and statistical approaches for the study of passive, active, digital, multidimensional, and adaptive filters. Most of the filters considered were linear although the theory of nonlinear fi...
