Automated Visual Inspection of Lyophilized Products via Deep Learning and Autoencoders
Manual visual inspection of every sterile parenteral product for defects is costly, cumbersome, and inconsistent. Industry standard currently relies on a semi-automated method, but the percentage of vials that require additional human inspection is high, at 30%. Using deep learning can help reduce …
