(EN) IMAGE PROCESSING METHOD
(FR) PROCÉDÉ DE TRAITEMENT D'IMAGE
Abrégé
(EN)
An image processing method using an algorithm which incorporates simulated annealing by parallel Markov chains, the calculation of fitness values of states of the Markov chains which have substantially the same simulated annealing temperature, the calculation of the standard deviation of these fitness values, and the use of this standard deviation in setting the simulated annealing cooling schedule. The method may be used to delineate an object of interest in an image against a background by estimating the boundary of the object and optimising the fit of the region within this boundary to the region occupied by the object.
(FR)
La présente invention se rapporte à un procédé de traitement d'image utilisant un algorithme, qui comprend : un recuit simulé par des chaînes de Markov parallèles; le calcul de degrés de compatibilité d'états des chaînes de Markov qui ont sensiblement la même température de recuit simulé; le calcul de l'écart type entre ces degrés de compatibilité; et l'utilisation de cet écart type pour définir le programme de refroidissement du recuit simulé. Le procédé selon l'invention peut être utilisé pour démarquer un objet d'intérêt dans une image par rapport à un arrière-plan, par estimation de la limite de l'objet et optimisation de la taille de la région à l'intérieur de cette limite par rapport à la région occupée par l'objet.
