Abstract
The E -filter is a homomorphic filter proposed by D.J.H. Moore and D.J. Parker (1973) which differentiates the small and large amplitude components of a signal. A description is given of a generalization of the E -filter to include a control parameter. Selective tuning of this parameter causes the behavior of the E -filter to range from linear to highly nonlinear. It is found that the E -filter can be simply implemented and has several properties which make it attractive for use in edge detection problems. The superiority of the E -filter to sale-space filtering for edge detection in one-dimensional systems is shown
