Abstract[English]
It is disclosed a method for processing a fluorescence image for detection of microorganisms in a sample, comprising: - Receiving a fluorescence image that has been acquired from a sample container comprising a plurality of wells of at least two different sizes, and the fluorescence image comprises a plurality of signal regions corresponding respectively to each well, and - Processing the fluorescence image to classify at least one considered signal region as positive or negative, comprising: o For each signal region, selecting a subset of pixels, computing an indicator of the intensity of the selected subset, o For each well size, computing statistical features (230) of the indicator of the intensity of selected subsets of pixels, computed for a plurality of signal regions corresponding to said well size, and Determining whether the considered signal region is positive or negative, by applying a trained classifier algorithm (240).[French]
Est divulgué un procédé de traitement d'une image de fluorescence pour la détection de micro-organismes dans un échantillon, comprenant : la réception d'une image de fluorescence qui a été acquise à partir d'un récipient d'échantillon comprenant une pluralité de puits d'au moins deux tailles différentes, et l'image de fluorescence comprend une pluralité de régions de signal correspondant respectivement à chaque puits, et le traitement de l'image de fluorescence destinée à classifier au moins une région de signal considérée comme étant positive ou négative, consistant à : pour chaque région de signal, sélectionner un sous-ensemble de pixels, calculer un indicateur de l'intensité du sous-ensemble sélectionné, pour chaque taille de puits, calculer des caractéristiques statistiques (230) de l'indicateur de l'intensité de sous-ensembles de pixels sélectionnés, calculés pour une pluralité de régions de signal correspondant à ladite taille de puits, et déterminer si la région de signal considérée est positive ou négative, par application d'un algorithme de classificateur entraîné (240).
