Robust Etimates in Dark Current Suppression
Original language description
This paper is devoted to noise suppression in astronomical images. These are contamined by thermally generated noise, called the Dark Current, which occurs in Charge Coupled Devices that are used as image sensors in astronomical science. Many basic statistical and ltering methods have been studied for Dark Current elimination. Applied algorithms must be sensitive to processed data, i.e., must not remove important objects and information. This paper introduces denoising methods based on the robust statistics, mainly on L and M-estimates. Proposed methods are applied to the real astronomical data. Results of used filters are compared from vizual point of view and also by Signal to Noise Ratio characteristic.
