Abstract
The contrast of an image is enhanced by converting pixels of detail images of a multi-scale digital representation of the image according to a conversion function. The conversion function is monotonically increasing and odd and provides maximum amplification within an intermediate subrange of pixel values of a detail image which subrange is considered critical. Furthermore the slope of the conversion function has a local maximum and a local minimum.
