METHOD AND APPARATUS FOR NON-CONTACT SIGNATURE IMAGING |
摘要 |
A portable, hand-held apparatus for capturing a gray scale image of a signature within a box having fiducial marks in the corners. Portions of the image outside the box are trimmed away and the box is oriented and scaled to a standard size and shape. Signature storage requirements are minimized and signature recognition is facilitated by thresholding the gray scale image and thinning the strokes of the signature to an image width of one pixel.
