Abstract
In this paper we describe the implementation of the
algorithm for local contrast enhancement published by Caselles et al. in 
1999.
This algorithm was the first designed explicitly to increase the contrast
while preserving the so-called 'shape structure' of the image, that is, its
set of level sets. According to the mathematical morphology school,
artifacts are created when this structure is modified.
The original algorithm is described and also two alternative implementations
are proposed, which limit the over-enhancement of noise.
