A method for recognizing user based on different kind sensors and an apparatus thereof

摘要

PURPOSE: A heterogeneous sensor fusion based user recognition device and a method thereof are provided to securely recognize a user by using probability distribution and an uncertainty model. CONSTITUTION: A modality sensor(100) senses the modality of a subject to be recognized through the different modality sensors. A recognizing part certifies the subject by comparing the reliability range of an uncertainty model with the sensed modality. The modality sensor comprises two or more among a thermal image camera, a video camera, and a microphone. The uncertainty model senses the modality of the recognizing subject and creates by the probability distribution of the modality.
