Products Semantic Data Extraction - White Paper OCR Preprocessing - White Paper Assertion Extraction -   Workflow Integration -   OCR/Image Enhancement Neurogy's OCR Preprocessing Module greatly improves the accuracy of OCR from both high quality and marginal documents. It removes graphical lines, detects lines of text, automatically detects and enhances dot-matrix, and separates lines of text according to font size and style, removing this load from the OCR engine. It also detects and removes random noise and patterned noise, rendering shaded (and usually unreadable) portions of invoices legible.
