Information processing apparatus and image reading apparatus judging title of read document

Abstract

In an image reading apparatus, a character area extractor extracts character areas from a document image in units of rows. A title reliability calculator calculates a title reliability level of each character area using a feature quantity data set and a machine learning model. A character recognizer converts character areas of which title reliability levels exceed a threshold into text data. A title judger collates text data with a title candidate. In a case in which one piece of text data coinciding with a title candidate is judged and detected, the title judger sets the text data as a title of the document image. In a case in which a plurality of pieces of coinciding text data are judged and detected, the title judger sets text data of which a title reliability level is the highest among the detected pieces of text data as a title of the document image.
