Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0023] Aiming at the problem that the existing column separation method cannot obtain the ideal column separation effect for complex handwritten layouts, the embodiment of the present invention proposes a layout column separation method and device, which takes the entire image as the analysis object, and finds the line along Y through blank segment analysis. The column dividing line of the axis divides the entire image into multiple columns, that is, the column division results based on the overall analysis.

[0024] Further, on the basis of the column division results based on the overall analysis, each column is taken as an analysis object, and for each analysis object, the text lines are merged into columns wi...

Abstract

The present invention discloses a layout column division method and device. The method comprises the steps of obtaining a column to-be-divided text image; scanning the whole column to-be-divided textimage along a Y axis, and saving the space segments in an X axis; scanning the space segments separately from top to bottom and / or from bottom to top along the Y axis to obtain a first set of segmentation lines and / or a second set of segmentation lines; according to the first set of segmentation lines and / or the second set of segmentation lines, obtaining the column division results based on the overall analysis. By utilizing the method and the device of the present invention, and aiming at the complex hand-writing layout, an ideal column division effect also can be obtained.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for dividing a layout into columns. Background technique [0002] With the development of computer science and technology, the ability and level of automatic information processing has also been significantly improved. The electronic application of documents has pervaded all aspects of people's life and work, brought about huge changes in the way of work and life, and also profoundly affected the field of education. The analysis and column division of document layout is one of the essential steps in the process of document digitization. The accuracy of its analysis directly affects the result of document digitization, so it has always been valued by researchers of related technologies. [0003] The existing mainstream method for document layout column division: Based on the consideration that the columns in printed documents are mostly regular rectangles, thro...
