Abstract (en)
The invention relates to a method for sorting security documents, preferably banknotes, wherein from the reflection of light in a wavelength range of approximately 400-500 nm of at least a part of a security document a degree of soiling of the security document is determined. In one embodiment the B component from the RGB components of a colour image is used for determining the reflection of light in the wavelength range. In an alternative embodiment the wavelength range has been selected from approximately 400-450 nm, preferably approximately 410-430 nm.
