Abstract (en)
[origin: WO2022023646A1] The invention relates to a method for predicting labels associated with a digital image, comprising a prediction phase consisting of: - supplying the image (I) to a segmentation neural network (SN) configured to predict a classification of the pixels of the image in a first set of classes; and, - supplying at least part of this classification to a classification neural network (CN), configured to predict a set of labels for said image from the classification P of the pixels; said segmentation and classification neural networks being determined by a training phase comprising, for each image of a training set, the first and second steps; and the determination of a location of the background of said image, from the classification of the pixels, and the optimisation of the weights of the neural networks, according to a set of cost functions configured, by iteration, to maximise the quality of the set of labels as a function of labels previously established and associated with the image, and to maximise the probability of not predicting any label for the background.
