Paper Abstract

Synthesizing document images is a cost effective way to create a large test database and allows researchers to control typesetting and noise variables. Yet the effectiveness of using synthesized images in optical character recognition (OCR) research has not been extensively investigated. In this project, three kinds of test databases were used to study the performance of OCR devices: digitized `real world' documents, page images synthesized from ASCII files, and the synthesized images printed and digitized. The cleanest synthesized images were not necessarily recognized most accurately. Our results suggest that, in addition to typographical features and noise, linguistic features affect the performance of an OCR device.
