"This paper is devoted to the dark current suppression in astronomical and multimedia images using the wiener filtering. We consider dark current represented by dark frame as a white impulsive noise generated in CCD sensor. The wiener filter is then set up accordance to measured second sample moments at CCD at chosen temperature range 268 K to 293 K. Furthermore, the temperature dependency of the second sample moments was fit by exponential regression. Hence, we are able to find sample moment and suppress dark current at given temperature. The measurement was done at SBIG ST8 camera." . "Kukal, Jarom\u00EDr" . . "\u0160vihl\u00EDk, Jan" . . "Bellingham, WA" . "Proceedings of SPIE 8499, Applications of Digital Image Processing XXXV" . .
