Methods and a computing device for determining whether a mark is genuine

According to various implementations, a computing device receives an image of a candidate mark and uses the image to create a profile of a feature of the mark. The computing device filters out, from the profile, all spatial frequency components except for a first band of spatial frequency components...

Abstract According to various implementations, a computing device receives an image of a candidate mark and uses the image to create a profile of a feature of the mark. The computing device filters out, from the profile, all spatial frequency components except for a first band of spatial frequency components, resulting in a first filtered profile for the feature. The computing device repeats this filtering process for a second band of spatial frequency components, resulting in a second filtered profile for the feature, and may repeat this filtering process for further spatial frequency bands. The computing device compares the first filtered profile of the candidate mark with an equivalent first filtered profile of a genuine mark, and may repeat this process for further filtered profiles.
