Steps include (a) image spectral analysis, (b) model training, and (c) classification of new objects to provide classification probabilities. For a new field-find object, an examiner would use (a) to image the object and perform (c) for object classification, using a model trained in (b) on samples of the same class to guide forensic conclusions.
