End-to-End Unsupervised Document Image Blind Denoising

Understand

Removing noise from scanned pages is a vital step before their submission to the optical character recognition (OCR) system.

• Most available image denoising methods are supervised where the pairs of noisy/clean pages are required.
• However, this assumption is rarely met in real settings.
• Besides, there is no single model that can remove various noise types from documents.
