In a method according to the invention, repeated patterns are identified in a strip-like product. In the method the strip-like product is observed by at least one camera, and at least one digital image signal comprised of pixels is created for inspection. The image signal is searched for anomalies (21, 22) comprised of one or more pixels. A search image (23) is created of any detected anomaly (21, 22) and its neighbourhood, and the search image is used to convolute the image signal being examined, creating a response image signal. The response image signal is used to determine image areas in the image signal being examined that are substantially similar to the search image (23). |
