Title (EN) VECTOR CORRELATION SYSTEM FOR AUTOMATICALLY LOCATING PATTERNS IN AN IMAGE
(FR) SYSTEME DE CORRELATION VECTORIELLE POUR LOCALISER AUTOMATIQUEMENT DES MOTIFS DANS UNE IMAGE
Abstract:
(EN) The present invention relates to a combined approach of image and template correlation, and vector correlation wherein edge detection and pattern searching are joined in a single operation to provide great flexibility without requiring extensive computational facilities. A template is devised from a sparse set of coordinate points that model only the important edges of an object to be located within an image. Different templates are dynamically reconstructed as an estimation of the object location within the image becomes more precise.
(FR) L'invention concerne une approche combinée de la corrélation image/modèle et de la corrélation vectorielle, dans laquelle la détection des bords et la recherche des motifs sont associées en une seule opération, de façon à donner une grande souplesse sans nécessiter des équipements informatiques lourds. Un modèle est divisé à partir d'un ensemble clairsemé de coordonnées qui modélisent uniquement les bords significatifs d'un objet que l'on cherche à localiser dans une image. Différents modèles sont dynamiquement reconstruits au fur et à mesure que l'estimation de la localisation de l'objet à l'intérieur de l'image se précise.
