Zusammenfassung: | To make it possible to semantically disassemble and recognize a plurality of different tables that are combined.SOLUTION: An information processing device performs table recognition for an input image including a combined table area in which different table areas are combined. The information processing device performs character recognition processing at least on the combined table area in the input image, extracts an item name from a character string obtained as a result of the character recognition processing, and, if an item name that is different from one item name is detected at a position advanced in one direction in a column or row starting from one item name in the combined table area, recognizes an area after the different item name as a different table area.SELECTED DRAWING: Figure 6
【課題】結合した異なる複数の表を意味的に分解し、認識することを可能にする。【解決手段】異なる表領域が結合してなる結合表領域を含む入力画像に対して表認識を行う情報処理装置は、入力画像のうち少なくとも結合表領域に対して文字認識処理を行い、文字認識処理の結果得られた文字列から項目名を抽出し、結合表領域内において、一つの項目名を起点とした列または行内において一方向に進んだ位置に一つの項目名と異なる項目名を検出したら、異なる項目名以降を異なる表領域として認識する。【選択図】図6 |
