AI agent struggles with PDF scans and OCR, missing key document sections

By PulseAugur Editorial · [1 sources] ·

The agent also struggled with a 14-page document where scanned pages, rotated sideways, were poorly transcribed by optical character recognition (OCR). To address these issues, a new approach involves checking character counts per page to identify unread sections and implementing a readability score to detect nonsensical OCR output, with added logic to re-OCR sideways pages in the correct orientation.
