摘要： The present invention relates to a method of determining a representation of a fingerprint pattern. The method comprises the steps of acquiring a reference signal indicative of an electric coupling between a hand surface having friction ridges and a reference sensing structure extending across a plurality of the friction ridges; and determining the representation of the fingerprint pattern based on the reference signal and a capacitive coupling between the finger and each of a plurality of sensing elements. The acquired reference signal can, for example, be used for controlling the sensing elements so that the sensing performed by the sensing elements is carried out using favorable timing, when the signal quality is good. Alternatively, or in combination, the acquired reference signal may be used for post-processing, whereby the signals/signal values obtained by the sensing elements are modified depending on the corresponding values of the reference signal.

摘要： A ridge flow based fingerprint image quality determination can be achieved independent of image resolution, can be processed in real-time and includes segmentation, such as fingertip segmentation, therefore providing image quality assessment for individual fingertips within a four finger flat, dual thumb, or whole hand image. A fingerprint quality module receives from one or more scan devices ridge-flow—containing imagery which can then be assessed for one or more of quality, handedness, historical information analysis and the assignment of bounding boxes.

摘要： Additional information regarding a fingerprint is estimated, with a given level of confidence, on the basis of characteristics of a set of minutiae corresponding to this print. Local descriptors are determined around some at least of the minutiae, so that they comprise, in relation to zones comprising additional information estimated with the given confidence level, values calculated on the basis of said information and, in relation to zones not comprising such information, erasures. The local descriptors determined are quantized according to a given number of integer values, a value being reserved for erasures. The quantized local descriptors are coded with the aid of an error-tolerant coding algorithm associated with a decoding algorithm devised to take account of errors and erasures. And a pseudo-identity is determined on the basis of some at least of the coded quantized local descriptors.
