Abstract
A method for determining skew angle () and location of a document in an over-scanned digital image is disclosed. A document is scanned to capture a gray scale image. The outline pixel () of a document from the captured gray scale image are connected (). An initial angle is set at zero and a x-minimum, y-minimum, x-maximum, and y-maximum of the polygon are determined (). A rectangular boundary () area based on the x-minimum, y-minimum, x-maximum, and y-maximum is calculated and recorded. The angle is recorded and the polygon is rotated z-degree. The process is repeated and a minimum boundary area is selected. An angle corresponding to the minimum boundary is the skew angle of the document.
