Chapter 7 Color 2D Region Metrics

As you see, Blew and Yellow powders, when finely mixed, appear to the naked eye Green and yet the colours of the component corpuscles are not thereby really transmuted, but only blended.

—Isaac Newton


In this chapter we discuss color metrics, color processing, color descriptors, color-based segmentation, and color correspondence, which the author believes are the key components of human vision. Several refinements to the synthetic eye and lateral geniculate nucleus (LGN) models are made to describe novel color spaces and biologically plausible color vision metrics. We postulate that the visual cortex provides feedback to the LGN and eyes to optimize the images for color, lighting and shading for hypothesis ...
