PROBLEM TO BE SOLVED: To further appropriately retrieve handwritten characters.SOLUTION: According to one embodiment, a handwritten character retrieval apparatus includes an acquisition unit, a feature extraction unit, an integration unit, a feature amount append unit, and a retrieval unit. The acquisition unit acquires a handwritten character string in units of a stroke. The feature extraction unit extracts a first feature amount unique to each of the strokes from the handwritten character string. The integration unit integrates the strokes into a plurality of sets. The feature amount append unit appends a second feature amount on the basis of the integration result to each of the strokes. The retrieval unit executes retrieval based on the first feature amount and the second feature amount. 【課題】より的確な手書き文字検索を可能にする。【解決手段】実施形態によれば、取得部、特徴抽出部、統合部、特徴量付与部、検索部を備える。取得部は、手書き文字列をストローク単位で取得する。特徴抽出部は、前記手書き文字列から、前記ストローク毎に固有の第１の特徴量を抽出する。統合部は、前記ストロークを複数の集合に統合する。特徴量付与部は、前記ストローク毎に前記統合の結果に基づく第２の特徴量を付与する。検索部は、前記第１の特徴量及び前記第２の特徴量に基づいて検索を実行する。【選択図】図１
