ABSTRACT:
The invention relates to a method and a device for detecting defects in textile webs. In order to rapidly adapt devices of this type to widely varying textile webs and to be able to operate such devices simply, brightness values are determined from the web and are supplied directly to a filter constructed as a neural network. The output results of the neural network can be displayed as grayscale values to indicate detected defects.
