Patent ID: 7236612

Claim:
A method of processing images (IN) of postal items by video coding, each image including address information, said images having been rejected by an automatic process of evaluating addresses by OCR, the method being characterized in that it consists: in producing an image attribute vector (AT) for each rejected image, the vector being constituted by confidence ratings (CV, CN) associated with the fields (V, N) of the address block forming the address information; in categorizing each rejected image by means of a cascade of filters (F 1 –F 4 ) acting on the confidence ratings of the attribute vector of said image, the filter levels in the cascade of filters identifying different rejection categories and determining for each rejection category a specific kind of processing by video coding; and when a rejection category corresponding to the rejected image is identified at a filter level, in causing said filtering to be followed firstly by processing by video coding (VC 1 –VC 4 ) specific to the rejection category so as to add to or modify the image attribute vector of the rejected image, and secondly by evaluation (E) of the attribute vector of the rejected image so as to be able to decide when to stop video coding on this rejected image.
