Abstract
A method whereby the image of a bar code is located in a digitized image of an object traveling along a conveyor belt; the orientation of the longitudinal axis of the code with respect to a reference system of the image is determined, and the code is scanned along lines parallel to the longitudinal axis of the code to generate respective vectors describing the pattern of the code image brightness signal along the respective line; and the vectors are digitized and projected to generate a real-number vector containing the coordinates of the brightness signal transition points indicating the shape and location of the code elements.
