A biometric system includes: a camera that captures a subject; a pressure information collection unit that detects a pressure value of at least one sole of the subject; a skeleton direction vector calculation unit that calculates a skeleton direction vector of the subject captured by the camera; a floor reaction force vector calculation unit that calculates a floor reaction force vector on a basis of information on pressure from the pressure information collection unit; and an analysis result output unit that displays, in a superimposing manner, the skeleton direction vector calculated by the skeleton direction vector calculation unit and the floor reaction force vector calculated by the floor reaction force vector calculation unit.

Biometric system and method

A free-moving piece (jellyfish sign) having a high probability of separation in the near future in an unstable plaque is clearly displayed. Ultrasonic tomographic images () of a cross section including an axis of the carotid artery are successively obtained. Using a threshold value which sets a surface () of the unstable plaque as a boundary between brightness and darkness, the plurality of ultrasonic tomographic images () are binarized. A difference is calculated between corresponding pixels of two binarized ultrasonic tomographic images so that a free-moving piece () is extracted and displayed overlapped over the ultrasonic tomographic image ().
