Abstract:
Disclosed are embodiments of systems and methods for eliminating or reducing the distortion in a scanned image. Embodiments of the present invention allow for the automatic pruning, de-skewing, and unwarping of an image using document layout information. In embodiments, dominant baselines may be selected by examining the letter regions on boundary baselines rather than examining the entire document layout. The dominant baselines may then be used to reduce distortion in the image. It shall be noted that present invention is robust enough to handle many types of content, including different languages, as well as documents with different layouts. The present invention may also be applied to images obtained from bound documents and flat documents.
