### Frequency Filter University Of Edinburgh

Frequency filter.Common names frequency filters brief description.Frequency filters process an image in the frequency domain.The image is fourier transformed, multiplied with the filter function and then re-transformed into the spatial domain.Attenuating high frequencies results in a smoother image in the spatial domain, attenuating low frequencies enhances the edges.
