Abstract
A method of processing a digital image to produce an improved digital image, includes receiving the digital image captured with a camera; determining a first vanishing point associated with the digital image; determining a second vanishing point associated with the digital image corresponding to a direction orthogonal the first vanishing point; determining a transform for modifying the digital image based on the first vanishing point and the second vanishing point; and applying the transform to the digital image to produce an improved digital image.
