Abstract
A computer-implemented method, system and a computer program product are provided for automatically detecting redaction blocks in an image file document by analyzing the document to identify any redaction block areas and then detecting location information for each redaction block area identified in the document which may be mapped to any associated text fragments in the document based on the location information for each redaction block area and text fragment in the document.
