Abstract :
Our topic is the potential of combining global gamut
mapping with spatial methods to retain the percepted local image
information in gamut mapping algorithms. The main goal is to
recover the original local contrast between neighboring pixels
in addition to the usual optimization of preserving lightness,
saturation, and global contrast. Special emphasis is placed on
avoiding artifacts introduced by the gamut mapping algorithm
itself. We present an unsharp masking technique based on an
edge-preserving smoothing algorithm allowing to avoid halo
artifacts. The good performance of the presented approach is
verified by a psycho-visual experiment using newspaper printing
as a representative of a small destination gamut application.
Furthermore, the improved mapping properties are documented
with local mapping histograms.
