Abstract

Computer vision is an important field in industrial/automation processes. Inspection by visual means can be a powerful tool in automatic control procedures. When operating with video signals, irregularities of the optical system must often be compensated. In particular, blur, geometric distortions and the unequal brightness distribution can lead to difficulties during further processing of an image. In the following, it is shown how the theory of neural networks can be applied in image correction. The weights of one single layer are trained for calibration. Using a suitable optimisation criteria the correcting system for images superimposed by noise directly results in a Wiener Filter. A pipeline processor simulates a neural network and operates in real time. After theoretical considerations, experimental results are given in this paper.
