Abstract
The method of processing objects, in which method a digital image (1) is obtained of the surface of each postal object, which image includes address information (2), and an identifier or time stamp for the postal object is associated with the digital image of the postal object in a video-coding system, is characterized by the fact that said digital image is processed in order to extract a signature that serves as an identifier. The signature comprises a first component representative of a physical characteristic of the digital image and a second component (SC) which is a textual description of the address block. This method can be used to implement immediate video-coding in a postal sorting machine without requiring a delay line.
