Abstract

　マッチング処理（Ｓ１）では、バウンダリ・マッチング・アルゴリズムを用いて、処理フレームFrame tの消失領域ΨをN×N画素単位で分割した分割消失領域ωtを、先に復元されたフレームFrame t-1の推定画像の対応領域ωt-1から再構成する。推定前処理（Ｓ２）では、ブロック・マッチング法を用いてFrame tの分割消失領域ωtの局所領域γtに対応するFrame t-1の推定画像の局所領域γt-1を求め、分割消失領域ωtの局所領域γtに含まれる全ての画素L×Lについて、Frame t-1の領域ωt-1の対応付けられた局所領域γt-1内から画素単位で第２の動きベクトルv＝(vx,vy)を算出する。原画像推定処理（Ｓ３）では、フィルタリング前処理（Ｓ２）で得られた結果から遷移モデルと観測モデルを定義し、カルマンフィルタ・アルゴリズムを用いて原画像の推定を行う。
