ABSTRACT:
Instead of trying to minimize some cost function of color errors, the present invention exploits physical models of scene-image relations. An image is first segmented into regions corresponding to objects in the physical world. Each object is then painted with a few levels of shades of the same chromaticity. This is motivated by the observation that physical objects are the basic units for human visual perception. Chromatic variations within an object surface tend to be grossly discounted by our color vision, and therefore, it is not necessary to render those variations accurately. Furthermore, since the shading across an object surface spans a much smaller dynamic range as compared to the whole scene, the limited number of color shades can be more effectively used within a segmented image region.
