  • PARAMETERISING AND MATCHING IMAGES OF FRICTION SKIN RIDGES
    Publication number: 20220383656
    Abstract: An apparatus and method configured to parameterise an image indicating friction skin ridges, the apparatus comprising means for: obtaining a first biometric parameter indicative of a group characteristic of a plurality of the friction ridges; obtaining a second biometric parameter indicative of one or more individual characteristics of one or more individual friction ridges of the plurality of friction ridges; and determining a third biometric parameter dependent on the first biometric parameter and dependent on the second biometric parameter. The first biometric parameter comprises a circular variance field indicative of variation of directions of the plurality of friction ridges. There is also provided a matching apparatus and method.

  • Computer-implemented print analysis
    Patent number: 10664715
    Abstract: A computer implemented method for automatic print analysis, the method comprising: receiving a first image wherein the first image shows one or more of: a latent print, a patent print, an impressed print, and an actual finger, palm, toe and/or foot; and wherein the first image includes characteristic features of at least one of a finger, a palm, a toe and a foot; creating an orientation field by estimating the orientation of one or more features in the first image, wherein the estimating comprises: applying an orientation operator to the first image, the orientation operator being based on a plurality of isotropic filters lying in quadrature.
