Abstract
A neurofilter is implemented as a neural network in which the weighting coefficients have previously been set, by an appropriate training procedure, such as to provide a desired form of filter response. The neurofilter is applicable to filtering of image data or serial data signals. Also, by training a neurofilter to produce output data based on amounts of error that occur in the output data from a conventional filter, a filter apparatus can be provided whereby the neurofilter compensates for errors in output data from the conventional filter. The design and manufacturing constraints on the conventional filter can thereby be substantially relaxed.
