| abstract
(eng) |
We present a novel multiimage restoration method based on the underlying spatial probabilistic image model for astronomical image restoration if degradation obeys a linear degradation model with the unknown possibly non-homogeneous point-spread function. The method assumes that for every ideal undegraded unobservable image several degraded observed images are available. Pixels in the vicinity of image steep discontinuities are left unrestored to minimise restoration blurring effect. |

Práce prezentuje novou víceobrazovou metodu restaurace astronomických obrazů založenou na prostorovém pravděpodobnostním modelu. Předpokládáme lineární degradační model s neznámou funkcí rozptylu bodu. Metoda předpokládá existenci několika degradovaných obrazových pozorování pro každý nepozorovatelný nedegradovaný obraz. Předpoklad reprezentace degradovaného obrazu pomocí simultáního kauzálního multidimenzionálního regresního modelu vede na rychlý adaptivní rekurzivní restaurační filtr |
