  • Rotation and position invariant optical character recognition
    Patent number: 5317652
    Abstract: A character recognition system wherein the flexibility of the recognition task is expanded for orientation independence, position independence, and orientation and position independence. The system also provides a technique for implementing concurrency in the processing to achieve high speed without sacrificing performance. The system is readily implemented on conventional machine vision computing systems.

  • Computer-based system and method for character recognition
    Patent number: 5214719
    Abstract: A character recognition system and method is disclosed which provides for the teaching and recognition of characters. The system includes an apparatus and method for obtaining an image which includes the character, and for sampling the character to create a plurality of sample points. A vector correlation is performed on these sample points which compares the stored points to those of known characters. The system also provides a precedence table for determining the correct order of recognition of any correlation of multiple characters.
