Pattern recognition method and device

Abstract

【課題】 検出対象の姿勢変動によって生じるみかけの変化に対応して、同じカテゴリーに属するがそれぞれ個性を持つ検出対象、たとえば車両や人の顔などを、増分符号を用いて検出できる。 【解決手段】 検出対象の姿勢変動によって生じるみかけの変化に対応したパターン検出を達成するために、検出対象の画像からなるデータベースから増分符号の統計的な性質を抽出し、その性質を用いた特徴ベクトルの学習によってパターン検出のための最適な識別器を設計するものであり、これを最も主要な特徴とする。 【選択図】図1
PROBLEM TO BE SOLVED: To detect a detection target having individuality though belonging to the same category such as a vehicle or a human face according to an apparent change caused by an attitude change of the detection target by use of an increment code. SOLUTION: This pattern recognition method is a method for extracting a statistical property of the increment code from a database formed by an image of the detection target, and designing an optimum identification device for pattern detection by learning of a characteristic vector by use of the property to accomplish the pattern detection corresponding to the apparent change caused by the attitude change of the detection target.
