Edge detectors and spectral image factorization
Irina V. Borisova, Pavel G. Popov · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1993
The authors consider the methods of detecting edge based on the Fourier transform. They show connection between this method and well-known enhancement/thresholding edge detectors. The quantitative and qualitative estimations of different methods of detecting edge are given.
