Wiener filtering in the process of dark current suppression
Original language description
This paper is devoted to the dark current suppression in astronomical 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 tomeasured second sample moments at CCD at chosen temperature range 268K to 293K. 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 atgiven temperature. The measurement was done at SBIG ST8 camera.
