CA 2729657

The present invention relates to a method and system for secure coding of arbitrarily shaped visual objects. More specifically, a system and method are provided for encoding an image, characterized by the steps of selecting one or more objects in the image from the background of the image, separating the one or more objects from the background, and compressing and encrypting, or facilitating the compression and encryption, by one or more computer processors, each of the one or more objects using a single coding scheme. The coding scheme also is operable to decrypt and decode each of the objects.

La présente invention concerne un procédé et un système de codage sécurisé dobjets visuels de formes arbitraires. Plus spécifiquement, linvention concerne un système et un procédé pour encoder une image, caractérisés par les étapes consistant à sélectionner un ou plusieurs objets dans limage à partir de larrière-plan de limage, séparer le ou les objets de larrière-plan, et compresser et chiffrer, ou faciliter la compression et le chiffrement, par un ou plusieurs processeurs dordinateur, chacun des objets utilisant une seule méthode de codage. La méthode de codage peut également être utilisée pour déchiffrer et décoder chacun des objets.
