Abrégé

Method for assigning a stonefruit to a predetermined class, in which the stonefruit is transported along at least one source of high-energy electromagnetic radiation such that at least a part of the radiation penetrates through the stonefruit to at least one camera thereto provided and is there captured by the camera to form a contrast image using the captured radiation after which the contrast image is processed by a processing unit which is provided to evaluate a pattern in the contrast image caused by a variation in the density or thickness of a material of the stonefruit corresponding to at least one predetermined feature of the stonefruit and to assign, based on the evaluation of the feature, the stonefruit to a predetermined class, characterised in that the feature mainly corresponds to the presence or absence of a slit in a pit of the stonefruit.
