Process for treatment of items, including a graphical classification of signatures associated with shipments.

摘要

Procedure processing mailpieces (P), wherein in a first pass selection ships form (12) a digital image of the surface of each of the shipments comprising information blocks (AD, AE, L ), it follows (13) each associated with shipping a digital signature (V-ID) which is a logical for sending identification and registers (16) in memory signature (V-ID) in correspondence with image information selection and wherein when a second sorting pass consignments takes place, is formed (41) again a digital image of said surface of each shipment to derive (42) a current digital signature (V-IdC) associated with shipping and it is sought between the signatures recorded in the first sorting pass a match with the current signature in order to retrieve by association sorting information, characterized by comprising the following steps: -is regrouped (43) signatures in categories signatures or graphical classes (CG) according to particular criteria of visual similarity to calculate (57) a mean signature value for each graphical class; It is 2348009 T3 He analyzes (60, 61, 62) for each graphical class activity considered a mean signature value for detecting significant activity of an information block in the digital images; -and the results of this activity detection for the concordance search exploited.
