Electroluminescence
Abstract: Electroluminescence (EL) is a kind of luminescence which is an optical and electrical phenomenon in which light is emitted by certain materials due to the passage of an electric current or a strong electric field. The mechanism behind electroluminescence is the radiative recombination, or spontaneous emission. The electrons get excited and release their energy as photons. The holes and electrons before recombining are separated either by doping the given material …

Image Preprocessing Techniques
Abstract: ABSTRACTPreprocessing method is an important step, specifically for low-quality picture images. This method is robust to lighting variations and produces images with very little noise and consistent stroke width. The process computes a “surface” of background intensities at every point in the image that performs adaptive thresholding based on this result. The surface is estimated by identifying regions of low resolution text and interpolating neighboring background intensities into these regions. …
