Abstract :
This paper1 focuses on an automatic model for contrast enhancement of digitized archive photographic prints. It exploits the relation between the change of contrast along scales and the Lipschitz regularity of the image for producing an adaptive enhancement. This strategy allows to drastically reduce typical effects as halo and noise amplification, resulting completely automatic thanks to the use of the visibility laws.
