Nowadays, biometric recognition is a mature technology that is used in many applications, offering greater security and convenience than traditional methods of personal recognition (2).</p><p>During the past few years, biometric quality measurement has become an important concern after a number of studies and technology benchmarks that demonstrate how performance of biometric systems is heavily affected by the quality of biometric signals (3). This operationally important step has been nevertheless under-researched compared to the primary feature extraction and pattern recognition tasks (4). One of the main challenges facing biometric technologies is performance degradation in less controlled situations, and the problem of biometric quality measurement has arisen even stronger with the proliferation of portable handheld devices, with <strong>at-a-distance and on-the-move acquisition</strong> capabilities. These will require robust algorithms capable of handling a range of changing characteristics (2). Another important example is forensics, in which intrinsic operational factors further degrade recognition performance.</p><p>There are number of factors that can affect the quality of biometric signals, and there are numerous roles of a quality measure in the context of biometric systems. This section summarizes the state of the art in the biometric quality problem, giving an overall framework of the different challenges involved.</p> http://dx.doi.org/10.1007/978-1-4899-7488-4_9129 http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:623099 1297 Encyclopedia of Biometrics Book Chapter 1287 Quality Measures in Biometric Systems 2015 2016-09-30T20:40:57Z 2457662.3617708 Quality Measures in Biometric Systems 500 0 plainlist list 1 [[:Publications:Quality Measures in Biometric Systems]] Quality Measures in Biometric Systems# QUERY6197b2b457cfa89c94d1749c17e46685 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Quality Measures in Biometric Systems# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Quality Measures in Biometric Systems# ERRe24f17e090c98448f3de99d03182b7b6
