Method for sorting the mail items including a management improved! of the exploration space of the signatures of items

摘要

In a method of sorting passes into a plurality of sorting postal items in a sorting machine sorting outlets to the accumulation, it uses a technique of identification of the mail items by the signatures of the image (v - id) derived from the images of the mail items. The mail items are transferred into the tanks between two sorting passes. The search for a match between a current fingerprint in the second sorting pass and of the impressions produced in the first sorting pass is carried out in a memory space for exploring containing a limited number of indentations. The optimization of the size of the exploration space is obtained by associating with the signatures and with the bins of the information of the destination (st) indicative of sorting outlets and time information (ts, supplied by a clock hb).
