Abstract

The method for sorting natural objects into different quality classes based on their properties comprises defining for each object (1) to be sorted a parametre set (s) which comprises a number of parametres that represent the properties of the object, and determining the quality class (C) of the object on the basis of the parametre set. In accordance with the invention, the parametre sets (s) of a number of objects (1) are divided into groups (g) of similar parametre sets, at least one group is selected to each quality class (C), and groups that have not yet been classified are then assigned to the quality classes based on their similarity to the groups that have already been classified, until all groups are classified, so that the quality class of an individual object is determined according to the quality class of the group which represents the parametre set of the object. In accordance with the invention, mathematical distances between the multi-dimensional parametre sets are used in the method as the measure of similarity between the parametre sets and between the groups.
