Summary

In a document processing system, the data in any text content take on a variety of sizes and fonts of characters, graphics, and pictures. Numerous algorithms have been proposed for document processing. The interpretation of graphics and pictures is achieved by image processing and computer vision accompanied with rule-based technologies alluded to in the descriptive paragraphs. Therefore, the document processing system is the state-of-the-art enterprise of automating and integrating a wide range of processes and representations for document perception. It integrates many techniques involved in computer graphics, image processing, computer vision, and pattern recognition. This chapter is organized as follows: Block segmentation and classification are presented followed by a rule-based character recognition system (CRS). The chapter describes Logo identification and presents the Fuzzy typographical analysis (FTA) for character preclassification.
