1. A method of processing postal objects, in particular packets, in order to read a postal address (AD) automatically on each object, the method including a step of assistance by video-coding, said method comprising the following steps for each object:

  • acquiring (10) a digital image of the object at a first level of resolution;

    detecting (20) in said digital image of the object one or more zones of interest (ZI) of the image each apparently containing a postal address;

    applying an automatic address recognition algorithm to each detected zone of interest in order to extract a postal address (AD) of said object; and

    if the automatic address recognition step fails, displaying each zone of interest (ZI) at a second level of resolution on a screen of a video-coding station on a screen context background (F) representative of said digital image of the object in order to enable an operator to perform semi-automatic processing (50) to read the postal address (AD) of said object, wherein the screen context background is displayed on the screen at a third level of resolution that is lower than said second level of resolution.
