Abstract

Method implemented by computer (16) for detecting a damage to a component (1), including: applying (212) a first neural network (40) to at least one multispectral image (25) of the component (1), formed by a plurality of images (30) of the component (1) in corresponding spectral bands, to generate a corresponding mask (62), which includes a respective plurality of pixels, each pixel of the mask (62) being relative to a corresponding portion of the component (1), the first neural network (40) being further such that each pixel of the mask (62) represents a corresponding first-level estimate, which is indicative of a probability that the portion of the component (1) to which the pixel refers is damaged; applying a second neural network (70) to a data structure (65) that is a function of the mask (62), to generate a second-level estimate (999), which is indicative of a probability that the component (1) is damaged; and detecting (228) whether the component (1) is healthy or damaged, based on the second-level estimate (999).
