Abstract:
A system of border detection on a document and for producing an image of the document is provided. In an exemplary embodiment, the system comprises: a frequency specific reflective border on the document; an image capture device; a filter tuned to the frequency of the reflective border; a border detection algorithm; and a processor communicatively linked to the image capture device, to the notch filter, and to the border detection algorithm. The image capture device is configured to capture an image of the document. The processor is configured to apply the filter to the captured image and to produce a second frame. The processor is further configured to apply the border detection algorithm to the second frame to determine a document border mask. The processor is further configured to apply the border mask to the captured image to produce a document image.
