How many times is an instance of a particular trait to be captured?Using a single sensor and a single instance of a particular trait, it is nevertheless possible to obtain distinct samples of that instance under different conditions (e.g., video images taken of a trait instance from different angles or voice recordings taken at different moments and with different speech content).These multi-sample systems may also be represented by a schema similar to that of multi-sensor systems. How many different biometric traits are to be captured?Biometric recognition systems may be designed to analyze a single biometric trait (i.e., unimodal systems) or various traits (i.e., multimodal systems).The particularities of the latter type of system are represented by the schema below.
