Image data output processing apparatus and image data output processing method
First Claim
1. An image data output processing apparatus which carries out an output process with respect to input image data, the image data output processing apparatus comprising:
- an image matching section that (i) extracts features of an image of the input image data and (ii) carries out a determination as to a similarity between the image of the input image data and an image of a reference document based on a comparison made between the features extracted and features of the image of the reference document stored in advance; and
an output process control section that controls the output process with respect to the input image data based on a determination result made by the image matching section, wherein the image matching section carries out a matching of the image of the input image data by use of a storage section which stores (i) features of each of images on a front side and a back side of a duplex reference document and (ii) an index for identifying a duplex document including the reference image, the index being stored so as to correspond to an index for identifying each of the images on the front side and the back side of the duplex document, the image matching section further including;
a voting process/candidate list creation section that extracts, in a case where the input image data is of a duplex document, for each of the images on the front side and the back side of the duplex document, (i) a reference image index of a reference image having a similarity which is not less than a predetermined value from the storage section and (ii) a reference document index corresponding to the reference image index from the storage section, so as to create a front side candidate list and a back side candidate list; and
a duplex document determination process section that determines, in a case where each of the front and back side candidate lists created include a reference image index that corresponds to an identical reference document index, that the images on the duplex document of the input image data are similar to the reference images that correspond to the identical reference document index, respectively.

Abstract
An image data output processing apparatus of the present invention, in a case where a reference document is duplex, causes a storage process section, in a storage mode, to store, at the time of storage, a DocID indicative of the reference document so as to correspond to an ID indicative of respective document images on front and back sides of the reference document. In a matching mode, in a case where a matching document is duplex, (i) an ID similar to that of the reference document and (ii) a corresponding DocID are extracted for each of the document images on the front side and the back side of the matching document, so as to create candidate lists for front and back sides of the matching document. If first candidates in the candidate lists correspond to an identical DocID, it is determined that the images are similar to each other, and if the first candidates do not correspond to the identical DocID, a determination result is corrected to a reference document that corresponds to the identical DocID. Thus, it is possible to realize an image data output process that can reliably control an output process, in the case where input image data is of a duplex document and includes a document image in which its output process is regulated.
