In this paper, we present a noise model for generating synthetic character databases to train Optical Character Recognition (OCR) systems. Nowadays, the emergence of new font typefaces requires an imperative task to automatically and rapidly generate synthetic training character databases. In addition, since the accuracy of the OCR systems deeply depends on(More)
The digitalization processes of bills produce frequently digital images with a mass of redundant background caused by rotation angles and misoperations in the scanning process. The redundant background occupies much storage space. First, this paper proposes a method that combines Hough transform and mathematical morphology to detect the skew. Secondly, the(More)
In an effort to control modern solid state power modules, a general purpose, multi function power system control board (PSCB) has been under development as a collaboration project between Pohang Accelerator Laboratory (PAL), Korea, and Stanford Linear Accelerator Centre (SLAC), USA. The PSCB is an embedded, interlock supervisory, diagnostic, timing, and(More)
