ABSTRACT:
A system and method for decoding printed alphanumeric characters from images or video sequences captured by a wireless device, including the pre-processing of the image or video sequence to optimize processing in all subsequent steps, the searching of one or more grayscale images for key alphanumeric characters on a range of scales, the comparing of the values on the range of scales to a plurality of templates in order to determine the characteristics of the alphanumeric characters, the performing of additional comparisons to a plurality of templates to determine character lines, line edges, and line orientation, the processing of information from prior operations to determine the corrected scale and orientation of each line, the recognizing of the identity of each alphanumeric characters in a string of such characters, and the decoding of the entire character string in digitized alphanumeric format.
