摘要

"Segmentation of a digital image of a postal object by processing Hough.For segmenting a digital image of a postal package in order to read automatically a postal address (AP) on the package.The process consists of dividing the image into blocks (20) image of the same size.To implement (30) on each block of the image a treatment based on a transformation of Hough to identify in the block of image is considered as a privileged direction of the distribution of the points of imageM in the said block considered,In group (40) blocks of contiguous image in the image and which have a privileged direction common to define (50) an area of interest which is rectangular in the grouping of these blocks containing registeredu00edguos so that rectangular area of interest has a longitudinal edge parallel to the direction of privileged policy,And implement (60) an algorithm of automatic recognition of addresses in the area of interest of the image in order to read automatically a postal address on the package.
