Aesthetics and entropy II: a critical examination

摘要

The proposal to use entropy as a metric for optimization of image processing has been subjected to further critical examination, on the basis of experiments with contrast adjustment, HDR imaging, bimodal brightness distributions, and unsharp masking. Consequently our original expectation that entropy may be a directly useful response metric for optimizing image processing now appears to us to be na?ve and limited in its applicability. One purpose of the present investigation is to ascertain the nature of these limits. We also infer from the unsharp masking studies that the human visual system (HVS) has evolved not so much to maximize information captured from the visual field as to enhance compressibility and to effect image simplification.
