Latest Patents

One of his latest patents is a fingerprint image processing system capable of simply processing minutiae. This system allows for the edition or correction of fingerprint images by adding true minutiae and deleting false ones. It formulates a minutia list that registers the location, direction, and relations of adjacent minutiae. The system can handle minutiae as images for editing and recognize them as data for correction. Additionally, ridge numbers between adjacent minutiae are included in the minutia relations, which can be extracted manually or automatically from the fingerprint image.

Another notable patent is an apparatus for automatic fingerprint classification. This invention utilizes radial scanning vectors to trace the space between adjacent ridge lines, including a core point. The radial distribution of the number of cross points from the core point serves as a clue for fingerprint classification.
