Patent ID: 7088873

Claim:
A method of bit-mapped image analysis comprising preliminary division of all analysis means at the disposal into two or more groups differing in accuracy of results; performing a multi-stage analysis, said analysis further comprising at least a primary analysis stage along with collection of supplemental data, said primary analysis further comprising at least parsing the image into objects, detecting among said objects those with distortion that embarrasses character recognition, preliminary recognition of said objects with the distortion, detecting among said objects those requiring more accurate analysis means to overcome the influence of distortion, said primary analysis stage using the analysis means from group of most inaccurate means; at least one profound analysis stage along with collection of newly appeared supplemental data, said profound analysis stage further comprising repeating of recognition of said objects with distortion that were not recognized at the previous stage taking into account the supplemental data obtained at the previous stage, detecting among said objects those requiring more accurate analysis means to overcome the influence of distortion, collection of newly appeared supplemental data, making a decision about the necessity of repeating of the profound analysis stage taking into account the whole supplemental data collected at the previous stages or finishing the analysis process, each subsequent profound analysis stage using the analysis means from the group of more accurate means.
