Systems and methods relating to document and fastener identification

This invention describes a system for automatically processing documents. It works by shining lights on a document from different angles and taking multiple pictures. These pictures are then used to create a "shadow profile" which helps to find the document's exact edges and detect if any fasteners, like paper clips, are present. If fasteners are found, a robot arm can remove them, specifically looking for edges thinner than 0.1 mm and recognizing inverted fasteners.

Why it matters: Filed before significant advancements in AI-driven computer vision. Identifying subtle features like thin edges and inverted fasteners from shadow profiles is now more robust with current machine learning models.
