Abstract
Aspects of the present invention are related to systems and methods for automatic content-boundary detection in a digital image. According to one aspect of the present invention a received image may be preconditioned to form a normalized image from which image-content edges may be detected. Projection histograms in the direction of a known skew angle associated with the image and the normal to the skew angle may be formed to determine image-content boundaries.
