Abstract
画像中の顔を検出する前処理としての従来のコントラスト補正は、画像の二乗平均や分散値による割り算が必要、局所部分全ての画素に対して演算必要のため、処理演算が大掛かりになる。入力画像選択部が画像から局所領域を選択し、フィルタ選択部が検出用のフィルタを選択し、入力画像選択部とフィルタ選択部からの出力を用い、選択局所領域の入力画像のフィルタ演算をフィルタ演算部で行い、一方、入力画像選択部からの入力画像の画素値の分布を正規化部で調べ、変換テーブルで分布情報を元に正規化係数を決定し、フィルタ演算部の出力結果にこの正規化係数を乗算器で乗算し、乗算結果を用いて、入力画像内部に顔が含まれるかの判定を行い、検出結果を出力する顔検出部とを備える。
