Abstract:
1. A method for recognizing distorted text in a computer image of the text, wherein the method uses at least one a priori defined recognition scheme for recognizing unknown characters, the method comprising the steps of: a) using the a priori defined recognition scheme, and identifying at least one recognition rule in the recognition scheme that provides appropriate recognition of words or partial words, b) using the identified at least one recognition rule on the computer image of the text to provide a first output stream including reliable recognized words and a second output stream including dubious recognized words, c) identifying at least one geometrical feature in the distorted text image related to actual characters encountered in the first output stream, and establishing at least one additional recognition rule in the recognition scheme based on the at least one geometrical feature, d) whenever there is a second output stream, providing an adaptation of rules in steps a), b) and c) before continuing recognizing words, and e) iteratively performing steps a), b), c) and d), until a predefined stop criteria is reached.
