Coarse Document Classification

摘要

Systems and methods coarsely classify unknown documents in a group or not with reference document(s). Documents get scanned into digital images. Counts of contours are taken. The closer the counts of the contours of the unknown document reside to the reference document(s), the more likely the documents are all of a same type. Embodiments typify contour analysis, classification acceptance or not, application of algorithms, and imaging devices with scanners, to name a few.

主权项

1. An imaging device, comprising:
a user interface; a scanner for converting an unknown input document and one or more reference documents to digital images; and a controller for executing instructions responsive to the digital images upon a user selecting a classifying application from the user interface, wherein the controller is further configured to determine whether or not the unknown input document belongs to a group with the one or more reference documents by determining and comparing counts of contours of the digital images corresponding to said each of the unknown input document and the one or more reference documents.
