Image Reconstruction Using an Array of Photoresistors and Kalman Filter

Abstract

On this paper we present a mechano-electrical system capable of scanning and acquiring images that are enhanced using Kalman filter. As photosensitive element we chose photoresistors that restrict the resolution of our system to their diameter. The whole system consists of three main parts: the scanning device, the acquiring circuit and finally an image processing stage. To process the image, we designed a Kalman Filter, that allows us to save two images, the one acquired directly from the mechano-electrical circuit and the one enhanced by the filter. Our system proposes a simple, small, low cost scanning solution that can be used as a camera for images that have little curves on their morphology.
