Patent number: 7412097Abstract: A process for detection of straight-line segments in a stream of digital data that are representative of an image (m, n) in which the contour points of said image each defined by the modulus and the orientation ? of their gradient in relation to a horizontal axis are identified. The stream of digital data is stored in the form of two successive lines, each of n points P(i, j), for each of the lines the n points of said line are extracted successively, and for each point Pc(i, j) extracted, the so-called current point, the three points having inferior coordinates Pa(i?l, j?l), Pb(i, j?l), Pd(i?l, j) directly neighbouring said current point are extracted, successively the value of the orientation of the current point Pc is compared with that of the neighbouring points Pa, Pb and Pd. The values of the orientations of the points Pb and Pd are compared, the result of a comparison is validated if the points are contour points and if the values of their orientation are close.Type: GrantFiled: February 28, 2006Date of Patent: August 12, 2008Assignee: Intermec IP Corp.Inventors: Khalid El Akel, Christophe Dumontier, Patrick Reuze, Serge Thuries, Jean-Michel Puech, Jean-Louis Massieu
