拡張型MHI を用いた人の動作認識

抄録

In recent years, elderly people who live alone have been continually increasing. Its number is equivalent to 31.4 percent of elderly population in Japan. In the worst case, they cannot cry for help because of diseases or sudden injuries. Therefore a system for watching over elderly people is strongly requested in our society. In order to realize such a system, this paper proposes a method of recognizing human motions employing an expanded MHI which uses FoE (Focus of Expansion) to recognize the motion toward the depth direction. The proposed method was applied to the recognition of 6 human motions including ‘fall down’ and satisfactory results were obtained.
