Definition

A biometric expert, or an expert in biometric recognition context, refers to a method that expresses an opinion on the likelihood of an identity by analyzing a signal that it is specialized on, e.g., a fingerprint expert using minutiae, a lip-motion expert using statistics of optical flow. Accordingly, there can be several experts associated with the same sensor data, each analyzing the data in a different way. Alternatively, they can be specialized on different sensor data. Multiple experts can address the issue of how expert opinions should be represented and reconciled to a single opinion on the authenticity of a client identity.

Introduction

In biometric signal analysis, the fusion of multiple experts can in practice be achieved as feature fusion or score fusion. In addition to these, one can also discern data fusion, e.g., stereo images of a face, and decision fusion, e.g., the decisions...
