摘要: An apparatus and method for processing a captured image and, more particularly, for processing a captured image comprising a document. In one embodiment, an apparatus comprising a camera to capture documents is described. In another embodiment, a method for processing a captured image that includes a document comprises the steps of distinguishing an imaged document from its background, adjusting the captured image to reduce distortions created from use of a camera and properly orienting the document is described.

摘要: A process and system to transform a digital photograph of a text document into a scan-quality image is disclosed. By extracting the document text from the image, and analyzing visual clues from the text, a grid is constructed over the image representing the distortions in the image. Transforming the image to straighten this grid removes distortions introduced by the camera image-capture process. Variations in lighting, the extraction of text line information, and the modeling of curved lines in the image may be corrected.
