Abstract: front page image
(EN) According to this embodiment, an overhead scanner device acquires images continuously, updates a background model of the surroundings of a medium on the basis of the continuously acquired images, calculates a variation amount from the background model, extracts a hand region on the basis of the variation amount, and removes the image of the hand region from the image of the medium.
(FR) La présente invention concerne, dans le mode de réalisation décrit, un dispositif numériseur de transparents qui acquiert en continu des images, actualise un modèle d'arrière-plan des environs d'un support sur la base des images acquises en continu, calcule une quantité de variation à partir du modèle d'arrière-plan, extrait une région de main sur la base de la quantité de variation, et élimine de l'image du support l'image de la région de main.
(JA)  本実施形態によれば、オーバヘッドスキャナ装置において、画像を連続して取得し、連続的に取得される画像に基づいて、媒体周辺の背景モデルを更新し、背景モデルからの変動量を計算し、変動量に基づいて、手領域を抽出し、媒体の画像から手領域の画像を除去する。
