1. A variable skew correction system, comprising:
- a processor; and
a de-skew application executable by the processor to transform scanned image data of a document exhibiting a variable skew condition to an output model representing a de-skewed image of the document by transferring pixel data for each of a plurality of raster lines of the scanned image data to the output model, wherein a variable spacing between at least two adjacent raster lines of the scanned image data is modified in the output model to correct non-linear distortion of the scanned image data.

8. A variable skew correction method, comprising:
-
generating, with a processor, an output model representing a de-skewed image of a document based on scanned image data of the document, the scanned image data indicating a variable skew condition; deforming, with a processor, another model to conform to the scanned image data; and transforming, with a processor, the scanned image data from the deformed model to the output model to correct non-linear distortion of the scanned image data. - View Dependent Claims (9, 10, 11, 12, 13, 14)
