Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, an example in the case where automatic block formation is performed on drawing objects (in the following description, simply referred to as objects as necessary) included in a structured document will be described. A structured document is a document formed of a markup language, and is a document in which a logical structure is defined by inserting tags showing the structure of the document into the document to perform management and processing in a computer. Therefore, although this document is text data, this document is document data that can be used without being limited by OS or software while having a complex document structure, and has a high degree of versatility.

[0019] figure 1 is a diagram showing an example of a system configuration of a document management device for performing page layout (block formation processing). exist figure 1 Among t...

Abstract

An object list LO in which information of each object included in a structured document has been collected in a list format is formed. Objects in which a distance in the vertical direction of a document is equal to a threshold value or less are included in one object group and the objects in the object group G are grouped as one group. After that, in the case where a length in the horizontal direction of each of circumscribed rectangles of two or more objects included in the object group G is equal to a length in the vertical direction or more and a length in the horizontal direction of at least one of the two or more objects is smaller than a threshold value, a block reforming process is executed. In the block reforming process, among the objects in the object group G, the objects in which the distance in the horizontal direction is equal to the threshold value or less are grouped as one object group GC.

Description

technical field [0001] The present invention relates to a document management device, a document management method and a computer program. More specifically, the present invention is applicable to block formation of drawing objects such as graphics, character strings, or images in a document. Background technique [0002] Hitherto, there is a block forming technique for block forming (dividing) an area of ​​a document image. As such a block formation technique, there is a method of applying image region separation (block selection) to image data of a document. According to this method, an area of ​​a document image is extracted by using a technique such as a histogram or a graph segmentation method. As a technique using such a method, there is a technique disclosed in Japanese Patent Application Laid-Open No. 05-40849. In Japanese Patent Laid-Open No. 05-40849, first, image data is scanned in the lateral direction as well as in the vertical direction, and a histogram havi...
