Abstract
A computer-assisted method to segment an image of an identification document that includes: accessing data encoding the image of the identification document that includes four curved corners connected by four edges; applying gradient filters to the image of the identification document to generate an edge map that reveals candidate edges that are substantially horizontal or vertical relative to borders of the identification document, the gradient filters including gradient maps that reveal horizontal as well as vertical alterations of image intensities; accessing data encoding models representing an expected range of curved corners, each model quantifying both the radial and angular extents of the curved corners; identifying combinations of candidate edges, each combination including four candidate edges that are connected at four corners; and selecting a combination of candidate edges by applying the models to each of the four corners formed by the four candidate edges of each identified combination.
