1. Method for recognizing text in a captured imagery having a plurality of frames, said method comprising the steps of:
- (a) detecting a text region in a frame of the captured imagery;
(b) applying optical character recognition processing (OCR) to said detected text region to identify potential text for said frame; and
(c) agglomerating the OCR identified potential text over a plurality of frames in the captured imagery to recognize the text in the detected text region.

Abstract
An apparatus and a concomitant method for detecting and recognizing text information in a captured imagery. The present method transforms the image of the text to a normalized coordinate system before performing OCR, thereby yielding more robust recognition performance. The present invention also combines OCR results from multiple frames, in a manner that takes the best recognition results from each frame and forms a single result that can be more accurate than the results from any of the individual frames.
