Abstract
A method of inspecting a moving web. The method includes imaging a sequential portion of the continuously moving web to provide digital information. The digital information is then processed with an initial algorithm to identify any regions on the web containing anomalies. Image information corresponding to any identified region within the digital information is then selected. The selected image information is then analyzed with at least one subsequent algorithm to distinguish actual defects from among the anomalies.
