摘要
The E-filter is a homomorphic filter proposed by Moore and Parker which differentiates the small and large amplitude components of a signal. In this correspondence, we describe a generalization of the E-filter to include a control parameter. Selectively tuning this parameter causes the behavior of the E-filter to range from linear to highly nonlinear. We have found that the E-filter can be simply implemented and has several properties which make it attractive for use in edge detection problems. We have also shown the superiority of the E-filter to scale-space filtering for edge detection in one-dimensional systems. © 1990 IEEE
