Suspicious Behavior Detection based on Case-Based Reasoning using Face Direction

This paper proposes suspicious behavior detection system by human motion data. In recent years, as our living space become informatization and intelligent. The intelligent space system react to person who entered in, it needs elements recognition about them. Therefore, the authors constructed suspicious behavior detection system based on case based reasoning. This system run in intelligent space established many camera devices as sensing device. The authors calculate three-dimensional coordinates about human motion using DLT (direct linear transformation) method. The authors describe experiment using stay area and stay time as input and propose system using face direction and moving speed as
