In this paper, we present an improved image formation model and propose a color image enhancement using single-scale retinex based on the model. In the presented image formation model, an input image is represented as the product of global illumination, local illumination, and reflectance. In the proposed color image enhancement, an input RGB color image is(More)
Capacitor miniaturization is directly related to improved energy density and power density, which are determined at the component and material levels for multilayer ceramic, electrolytic and polymer film classifications. The volumetric efficiency of a capacitor depends on capacitance value, operating voltage and equivalent series resistance. Permittivity(More)
