Abstract

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: ∘ For each signal region, ▪ selecting a subset of pixels, ▪ computing an indicator of the intensity of the selected subset, ∘ 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).
