As an alternative, both Cos(t) and dark-object subtraction algorithms offer viable correction techniques that are well documented and appear to be robust and reliable. KEYWORDS: atmospheric correction, full -cost model, Cos(t), Dark object subtraction, apparent reflectance, Lake Superior WebThe dark count may be subtracted if a dark count image is available that exhibits less noise than the dark count contribution in the image being processed . This last point is very important; if the dark count image to be subtracted has more noise than the image to be processed, then subtraction will actually lead to an increase in noise!
