Proper Display and Accurate Recognition of Document Images

ABSTRACT

Proper display and accurate recognition of document images are often hampered by degradations caused by poor scanning or transmission conditions. We propose a method to enhance such degraded document for better display quality and recognition accuracy. The essence of the method is in finding and averaging bitmaps of the same symbol that are scattered across a text page. Outline descriptions of the symbols are then obtained that can be rendered at arbitrary resolution. This talk will explain the algorithm and show how it performs on fax images and how it can improve OCR recognition accuracy.
