Abstract
1. Способ корректной ориентации изображений при автоматической печати, включающий выполнение следующих операций: ! выполняют выделение текстовых блоков; ! выполняют проверку, является ли число текстовых блоков N меньше заданного порога Т; ! в случае, если число текстовых блоков N меньше заданного порога Т, определения ориентации документа не выполняют; ! в случае, если число текстовых блоков N больше заданного порога 7, выполняют заливку нетекстовых областей белым цветом; ! выполняют преобразование RGB изображения в бинарное; ! выполняют вычисление параметров асимметрии текста asym0, asym90; ! выполняют вычисление коэффициентов по горизонтали - ah, и вертикали - av; ! выполняют проверку, является ли asym больше нуля и ah больше, чем av; ! в случае положительного результата проверки считают, что документ имеет корректную ориентацию; ! в случае отрицательного результата проверяют, является ли asym меньше нуля и ah больше, чем av; ! если asym меньше нуля и ah больше, чем av, производят поворот изображения на угол 180°; ! в случае отрицательного результата проверяют, является ли asym90 больше нуля и ah меньше, чем av; ! если asym90 больше нуля и ah меньше, чем av, производят поворот изображения на угол 90°; ! в случае отрицательного результата производят поворот изображения на угол 270°. ! 2. Способ по п.1, отличающийся тем, что операцию проверки корректности ориентации электронного представления страницы выполняют, исходя из распределения пикселей изображения в направлении сканирования и перпендикулярном направлении.1. The method of correct orientation of images during automatic printing, including the following operations:! select text blocks; ! checking if the number of text blocks N is less than a predetermined threshold T; ! if the number of text blocks N is less than a predetermined threshold T, the determination of the orientation of the document is not performed; ! if the number of text blocks N is greater than a predetermined threshold 7, fill the non-text areas with white; ! converting RGB images to binary; ! perform the calculation of the asymmetry parameters of the text asym0, asym90; ! calculating the coefficients horizontally - ah, and vertical - av; ! check if asym is greater than zero and ah is greater than av; ! in case of a positive result of the check, it is considered that the document has the correct orientation; ! in case of a negative result, check if asym is less than zero and ah is greater than av; ! if asym is less than zero and ah is greater than av, rotate the image by 180 °; ! in the case of a negative result, check if asym90 is greater than zero and ah is less than av; ! if asym90 is greater than zero and ah is less than av, rotate the image by 90 °; ! in case of a negative result, the image is rotated through an angle of 270 °. ! 2. The method according to claim 1, characterized in that the operation of verifying the correct orientation of the electronic representation of the page is performed based on the distribution of image pixels in the scanning direction and the perpendicular direction.
