Abstract:
The article describes special aspects of the organization of nonlinear filtering of image contours defined as a sequence of complex numbers. An effect of scale and rotation of the contour on the filtering result is studied. Changes in the contour spectra caused by different nonlinear filters are studied.

Keywords:
nonlinear filtering, image processing, complex-valued circuit, median filter, adaptive filter, sigma filter, homomorphic filter.
