Houghi teisendus

Houghi teisendus on tehnika, mida kasutatakse digitaalsetes piltides joonte, ringide ja muude geomeetriliste kujundite tuvastamiseks. Algselt patenteeris Paul Hough 1962. aastal ja populariseeris arvutinägemises Duda ja Hart 1972. aastal. Houghi teisendus teisendab pildiruumis olevad servapunktid parameetriruumi (akutsumisruumi) kõverateks, kus kollineaarsed või ko-tsirkulaarsed punktid koonduvad ja muutuvad kergesti tuvastatavaks.
