Abstract :
In order to investigate the local filtering behavior of
the Retinex model, we propose a new implementation in which
paths are replaced by 2-D pixel sprays, hence the name “random
spray Retinex.” A peculiar feature of this implementation is the
way its parameters can be controlled to perform spatial investigation.
The parameters’ tuning is accomplished by an unsupervised
method based on quantitative measures. This procedure has been
validated via user panel tests. Furthermore, the spray approach
has faster performances than the path-wise one. Tests and results
are presented and discussed.
