The research on OCRs for Indian scripts is still a challenging task. While a large amount of literature is available for the recognition of Roman, Chinese and Japanese language characters, relatively less work is reported for the recognition of Indian language scripts. They can recognize characters with different fonts and sizes as well as different formats including intermixed text and graphics. These systems can process documents that are typewritten, or printed. Today, reasonably efficient and inexpensive OCR packages are commercially available to recognize printed texts in widely used languages such as English, Chinese, and Japanese. The object of OCR is automatic reading of optically sensed document text materials to translate human-readable characters into machine-readable codes. Optical character recognition is usually abbreviated as OCR.
