Abstract
This invention is a method for rectifying an input digital image including warped textual information. The method includes analyzing the input digital image to determine a plurality of text line traces that track along with the warped textual lines in a substantially parallel fashion. The input digital image is subdivided into a plurality of vertical slices, each having associated first and second slice edges and an associated slice width. Vertical slice deformation models are formed for the vertical slices by identifying a plurality of text line traces that cross a particular vertical slice, and fitting a parametric function that predicts second-edge vertical coordinates for the text line traces as a function of corresponding first-edge vertical coordinates. A plurality of streamlines are formed responsive to the vertical slice deformation models. A global deformation function is formed by interpolating between the streamlines and is used to form a rectified image.
