I have a PDF manual consisting of technical drawing parts and textual parts. How can I understand which page the drawing is on, without relying on the title block that may be present? Is it possible to have an intelligent algorithm that at a glance (or through ML) can understand that there is a drawing on that page?
In this example it is evident that the left page is a drawing ... I don't want to rely on the rectangular areas above and below in the pages but understand (as a human understands) that there is a drawing on the left ...
