3次元の動き情報を利用した検討は十分に行われていない。認証手法で大きな問題として、別人が本人の行動をまねて認証を突破することがある。そこで我々は、まねのしにくい空中行動中の 3次元的な動きに着目し、奥や手前への動きから個人差を抽出する手法を考えた。特に個人差が生じると考えられるものに、行動時の「速さの揺らぎ」がある。我々は、行動中から速さの揺らぎに関する大きな変化が発生した個所を変化点とし、変化点間の情報を3次元ベクトルへの変換と符号化による簡便な識別システムの構築を行う。提案システムの精度を検証した結果、同一人物と別人とを識別可能であることが分かった。本稿では、 3次元データから個人差のある特徴を抽出する一連の手法の提案と、構築した特徴抽出手法により個人識別が可能かを調査した結果を報告する。","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"研究論文","subitem_description_type":"Other"},{"subitem_description":"Research
