A new color descriptor has now been proposed to embed color information into the framework of CENsus Transform histogram (CENTRIST), so that such a state-of-the-art visual descriptor can be further improved to categorize image scenes. In the proposed color CENTRIST descriptor, global structure characteristics are described by both gradients derived from intensity values and color variations bet...

General illumination using LEDs has enabled designers to have precise control of the intensity and color of an illuminated area. In this work, I investigate how these systems can dynamically adjust to create optimal lighting conditions in the built environment. By incorporating environmental feedback into a system control loop, i.e., illuminance or luminance measurements, the precise intensity ...
