With AutoOCR version 1.17.2 there is an option to delete empty pages before OCR processing. The detection of a page as a “Blank” via a set threshold. The default value is 1%. A page is recognized as “empty” if less than 1% of the pixels of a page are “not white”. This value must be adjusted if necessary to be processed scans, as it may be when scanning with impurities also that a blank page having “more pixels”, and certain pages are then not detected as empty. However, if the threshold is set too high, it may be that pages with little content are also recognized as empty and thus deleted.
