Perceptual Evaluation of Tone Mapping Operators with Regard to Similarity and Preference

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.
