Cooperative control based on reaction-diffusion equation for surveillance system

This paper proposes a new cooperative control model for the surveillance system which consists of plural Pan-Tilt-Zoom cameras and no central control unit. Each camera adjusts their observation area to decrease blind spots in the whole surveillance area by the control model based on reaction-diffusion equation. Simulation results have shown that the surveillance system is able to cover new blind spots when some cameras are removed or are rearranged in their placement.

Color management system with multilayer perceptrons

This paper has two objectives. The first is to explain our color reproduction procedure, especially our new gamut check and mapping method and comparative experimental results on it. The second is to discuss availability and effectiveness of multilayer perceptron (MLP) in the color reproduction fields. We will show problems and merits of MLP and its learning through experiments.
