摘要:
A template minutia set of a fingerprint comprising template minutiae and a template interest region is provided. Further, an input minutia set comprising input minutiae and an input interest region according to an input fingerprint is provided. The input minutia set is matched with the template minutia set. All matching template/input minutiae are determined. Furthermore, an updated template minutia set is determined dependent on the matching template/input minutiae and the non-matching template/input minutiae, and dependent on whether the template minutiae are inside the input interest region or outside of it and whether the input minutiae are inside the template interest region or outside of it.

A method for determining a degree of match between a search fingerprint and a reference fingerprint comprises the following steps: a) Extracting at least one first search feature from a first region of said search fingerprint thereby forming a local search feature vector, b) Extracting at least one second search feature from a second region of said search fingerprint thereby forming a global search feature vector, whereby said second region comprises said first region, c) Determining a first similarity degree by comparing said local search feature vector with a local reference feature vector, d) Determining a second similarity degree by comparing said global search feature vector with a global reference feature vector of said reference fingerprint and using said first similarity degree, e) Determining said degree of match from said second similarity degree.

An active noise control system is provided to specify an input transducer, an error transducer, an output transducer and an active noise controller for generating an anti-phase canceling acoustic signal to attenuate an input noise and to output a reduced noise. The active noise control system also performs on-line secondary path modeling. For this purpose the active noise control system comprises, in addition to known systems, a secondary path change detection circuitry (6), a signal distinguishing circuitry (7) and an auxiliary noise control circuitry (8), all of them being used to model said secondary path.
