The second-order neural network , which is made of adders and multipliers , corrects positional translations generated in a complex-log mapping unit to output the same result for the same object irrespective of the scale and/or rotation of the object . The present invention enables high-rate image pattern classification and recognition based on parallel processing , which is the advantage obtained in neural network models , because consistent neural networks and consistent network structure computation models are applied to all steps from the image input step to the pattern classifying and recognizing step .";
