ABSTRACT:
A method of sorting sorting objects within a bulk of objects from a heterogeneous population is provided. The bulk of objects to be sorted has an inherent variation, and at least one class, having less variation than the originally inherent variation of the bulk, is separated from the bulk. This lesser variation represents a quality of composition with reference to any organic material of the objects within the bulk. The method comprises the steps of distributing each of the objects to be separated as a separate object in a sorting device; exposing the separate object to energy emitted from at least one energy source; recording from at least one point of the separate object by means of at least one sensor a first multivariate signal; predicting or classifying, by means of a calibration method previously performed on a subset of the population, between the first multivariate signal and the quality of composition, a second signal expressing the magnitude of at least one quality variable of univariate variation; and separating the separate object from the sorting device to the at least one collected class in dependence on the magnitude of the at least one quality variable of the second signal from the at least one point.
