Original Abstract

The paper describes restitution of geometrical distortions and improvement of signal-to-noise ratio of auto-fluorescence retinal images, finally aimed at segmentation and area estimation of the lipofuscin spots as one of the features to be included in glaucoma diagnosis. The main problems – geometrical and illumination incompatibility of frames in the image sequence and a non-negligible shear distortion in the individual frames – have been solved by the presented registration procedure. The concept and some details of the MI-based regularized registration, together with evaluation of test results form the core of the contribution.

Příspěvek se zabývá restitucí geometrického zkreslení a zlepšením poměru signálu k šumu u autofluorescenčních obrazů sítnice, s konečným cílem segmentace a odhadu velikosti oblastí lipofuscinu jako jedním z příznaků glaukomu. Podstatným problémem je přitom nekompatibilita snímků z posloupnosti v důsledku střihového zkreslení obrazů. Příspěvek popisuje koncept metody založené na užití kritéria vzájemné informace a současně informuje i o výsledcích testů.
