CA 2500264

A method and apparatus for automatically determining salient features (308) for object classification is provided. In accordance with one embodiment, one or more unique features are extracted from a first content group of objects to form a first feature list, and one or more unique features are extracted from a second anti-content group of objects to form a second feature list. A ranked list of features is then created by applying statistical differentiation between unique features of the first feature list and unique features of the second feature list. A set of salient features (308) is then identified from the resulting ranked list of features.

L'invention concerne un procédé et un appareil permettant de déterminer automatiquement des traits saillants (308) pour effectuer une classification par article. Selon un mode de réalisation, un ou plusieurs traits uniques sont extraits d'un premier groupe de contenu d'objets pour former une première liste de traits, et un ou plusieurs traits uniques sont extraits d'un second groupe anti-contenu d'objets pour former une seconde liste de traits. Une liste par ordre d'importance de traits est alors créée par application d'une différentiation statistique entre des traits uniques de la première liste de traits et des traits uniques de la seconde liste de traits. Un ensemble de traits saillants (308) est identifié de la liste de traits classés par ordre d'importance obtenue.
