Color image enhancement and evaluation algorithm based on human visual system

We propose a novel color image enhancement method, the human visual system controlled color image enhancement and evaluation (HCCIEE) algorithm, and apply it to color images by considering natural image quality metrics. This HCCIEE algorithm is based on a multiscale representation of pattern, luminance and color processing in the human visual system. Experiments illustrate that the HCCIEE algorithm can produce distinguishing details while avoiding artifacts, which often occur in conventional multiscale enhancement methods, as well as producing images that appear as similar as possible to the viewer´s perception of actual scenes.
