Abstract
A digital signal representation of an image is normalized by applying a normalization parameter to all pixels of the digital signal representation of the image or to the pixels of a multi-scale representation of the image. The normalization parameter can be derived from the digital signal representation itself or from a multi-scale representation of the image. Different criteria for deriving the normalization parameter are disclosed.
