ABSTRACT:
The method of processing images (IN) including address information by video coding consists in identifying, for each image rejected by a process for automatically evaluating addresses by OCR, a rejection category corresponding to the rejected image by means of a cascade of filters (F1–F4) applied to confidence ratings in the image attribute vector associated with the rejected image, and when the rejection category corresponding to the rejected image is identified at a filter, in causing said filtering to be followed firstly by operator encoding (VC1–VC4) specific to the rejection category so as to add to or modify the image attribute vector associated with the rejected image, and secondly by evaluating (E) the image attribute vector associated with the rejected image so as to be able to decide when to stop video coding for the rejected image.
