Abstract:
Disclosed are embodiments of systems and methods for eliminating or reducing the distortion in a scanned image. In embodiments, the image is segmented into foreground and background pixels. Foreground pixels may be grouped into “letters.” Using index-based searching, “letters” may be grouped into “words” and “words” may be grouped into baselines. One or more dominant baselines may be selected and the characteristics of the dominant baseline or baselines may be used to unwarp the image.
