Biometrics Standards and Face Image Format for Data Interchange - a Review

A biometric system is essentially a pattern recognition system. It compares the feature set data against the set of templates. Initially the biometric data is acquired from the subject, and from the acquired data the feature sets are extracted, these feature sets are used for comparison. With the ever-growing use of biometrics, it is the utmost need to use standard biometric systems. The biometric standards simplifies otherwise complicated choices, enables large scale integration, promote longevity and enables interoperability of the biometric systems. ISO/IEC has developed the biometric standards for all modalities. The part-5 of it contains the FaceImage Format for Data Interchange. It defines specifically a standard scheme for codifying data, describing human faces within a compliant data-structure. In order to enable applications that run on a variety of devices, including those with limited resources and to improve face recognition accuracy; the specification describes not only the data format, but also additional requirements, namely: scene constraints; photographic properties; digital image attributes.
