Abstract:
1. A method for determining the physical fitness of documents, the method comprising the steps of: (a) passing a document past an image sensor; (b) illuminating said document sequentially using multi-mode illumination, wherein the document is divided into discrete successive sections and a predetermined illumination mode is applied to each section as the document passes said image sensor until the entire document is imaged, producing an interleaved, multi-mode image of the document; (c) applying a multi-dimensional transformation function to said interleaved, multi-mode image to generate a composite measurement; and (d) projecting said composite measurement onto an empirically determined fitness vector to yield a scalar fitness value for said document; wherein the image sensor is a line scan camera and a predetermined illumination mode is applied to each scan line.
