Method for realizing blank page detection based on morphological transformation

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 practi
