Abstract:
Seven tone mapping methods currently available to display high
dynamic range images were submitted to perceptual evaluation in
order to find the attributes most predictive of the success of
a robust all-around tone mapping algorithm.
The two most salient Stimulus Space dimensions underlying the perception of
a set of images produced by six of the tone mappings were revealed
using INdividual Differences SCALing (INDSCAL) analysis;
and an ideal preference point
within the INDSCAL-derived Stimulus Space was determined for a group of
11 observers using PREFerence MAPping (PREFMAP) analysis.
Interpretation of the INDSCAL results was aided by
pairwise comparisons of images that led to an ordering of the images according
to which were more or less natural looking.
