Abstract :
A new approach is presented for dealing with the extraction of block address destination (BAD) on flat mail pieces. It is based on the construction of a pyramidal data structure which represents the image with a multi-resolution approach, so that much independence is provided with respect to variable parameters such as the size of characters, number of lines, and handwritten or machine printed. A top-down analysis is then performed on the pyramidal structure to interpret the various blocks segmented and their relationship between every level of the pyramid. Results are given in order to demonstrate the performances of this method
