Abstract (en)

[origin: WO2019106179A2] The present invention relates to a method for characterizing a sample using a set of spectral images of the sample to be characterized, which have been previously acquired, in particular by infrared thermography or spectral imaging, and to at least one neural network, the method comprising the steps of: - generating at least one volume of values of a parameter observed from said spectral images for a plurality of coordinates of the pixels of the images and a plurality of acquisitions, - extracting at least one set of input data from said data volume, said input data corresponding to the values of the observed parameter for a pixel of the same coordinates according to different acquisitions, wherein at least one transformation function has been applied to said values, - training said at least one neural network using the input data to extract at least one characteristic of the sample to be characterized.
