Abstract

The invention, which belongs to the field of intelligent identification in the machine vision industry, discloses a method for realizing blank page detection based on morphological transformation. Themethod is characterized by realizing automatic detection on a blank page rapidly and accurately based on the morphology. According to the basic principle, morphological top hat transformation is carried out on an original image to remove a background part of the image; mean value filtering is carried out by using a structure element with a font size; and then according to a proportion of points with grayscales exceeding a certain threshold value in the image, determining whether a current page is a blank page. According to the method disclosed by the invention, with focus on a detection speed, the method employs some effective ways with simple principles. And the experiment results show that the method disclosed by the invention has high-efficiency and quick effects, high identification precision and great practical value.

Description

technical field [0001] The invention relates to the field of intelligent recognition in machine vision industrial applications, in particular to a method for realizing blank page detection based on morphological transformation, which is used for automatic detection of blank pages in non-contact scanning. Background technique [0002] With the popularity of computer and network technology, electronic documents are accepted by more and more people because of their advantages of easy storage and utilization, and quick and easy dissemination. Therefore, the conversion of the original paper-based materials into electronic documents, that is, the digitization of paper documents, is increasingly used in daily office work and in library material management. [0003] As a new digitalization method of paper documents, non-contact scanning has been more and more applied, and there is still room for improvement. Non-contact scanning adopts the method of turning pages to scan, and scans...
