Patent

CA 2500805

A system and method for performing interactive and automated tissue image analysis and region of interest identification is provided, with global training database and variable-abstraction processing in cytological specimen classification and laser capture microdissection applications. The invention provided three-stage processing with flexible state transition that allows image recognition to be performed at an appropriate level of abstraction. The three stages include processing at one or more than one of the pixel, subimage and object levels of processing. Also, the invention provides both an interactive mode and a high-throughout batch mode which employs training filed generated automatically.

L'invention concerne un système et un procédé qui permettent d'analyser des images tissulaires et d'identifier une région d'intérêt pour des applications de traitement telles que la microdissection laser. L'invention prévoit un traitement en trois étapes avec une transition d'états flexible grâce auquel une reconnaissance d'images se fait à un niveau approprié d'abstraction. Les trois étapes comprennent un traitement effectué au niveau d'un ou de plusieurs des niveaux de traitement, à savoir pixels, sous-image et objet. L'invention concerne également un mode interactif et un mode de traitement par lots à haute capacité qui fait intervenir des fichiers de formation générés automatiquement.
