In a raw photographic image, the observed colors are a mixture of material reflectance and colored illumination. For further processing, the color influence of the light source is often considered a disturbance. In such cases, it is desireable to neutralize the color of the light source, often referred to as white balancing. Successful white balancing often requires an estimate of the color of ...

A laboratory human factors experiment was conducted to understand the color rendering properties of various LED-based reading lights. Human subjects rated their preference for a given scene illuminated by a test light source compared to an identical scene illuminated by a reference light source. In another experiment the same subjects viewed and rated the scenes individually when illuminated by...

Color transparency, the reduction of initial-state or final-state interactions in coherent nuclear processes, is a natural prediction QCD (quantum chromodynamics) provided that small-sized point-like configurations (PLCs) are formed high-momentum transfer, high-energy, semi-exclusive processes. I use Frankfurt-Miller-Strikman criteria for existence PLCs to show wave functions light-front hologr...
