Abstract
Disclosed are systems and methods which provide for scanning of information, such as characters or symbols, without requiring a controlled scan velocity. Preferred embodiments utilize an optical sensor in detecting attributes of information scanned and implement compensation techniques to remediate the effects of distortion and present information which may be identified to a high level of confidence. A known topology may be relied upon to present known markers in the scanned information, such as known blank or filled regions, patterns, or other observable traits and utilized with respect to a distorted scanned image to compensate for the effects of the distortion. Additionally or alternatively, vector based pattern recognition may be utilized in remediating distortion of a scanned image.
