:mod:`imgtools.filters`
=======================

.. currentmodule:: imgtools.filters

Basic spatial and frequency domain filters.

- Spatial domain filters
    * Edge: Laplacian, Sobel, Kirsch, etc.
    * Blurring filters: box blur, Gaussian, guided filter
- Frequency domain filters: based on rfft2
    * Laplacian
    * Gaussian highpass/lowpass
    * Butterworthhighpass/lowpass.
