Field: Computer technology (Electrical engineering)
Classification: CPC G  A | IPC A  G

Claim 0:
1. A device configured to determine a portion of at least one of broken grain or non-grain components in a stream of harvested material, the device comprising:
a camera configured to generate images of the stream of harvested material; and
an evaluation unit configured to estimate the portion in an image generated by the camera;
wherein the evaluation unit comprises a first-order classifier configured to estimate a first parameter of the stream of harvested material, and a plurality of second-order classifiers assigned to various values of the first parameter to estimate the portion in a stream of harvested material that has the assigned parameter value;
wherein the evaluation unit is configured to:
estimate, using the first-order classifier, at least one value of the first parameter using one or more images of the camera in order to identify a specific variety of crop;
select the second-order classifier, from the plurality of second-order classifiers, using the specific variety of the crop, wherein each of the plurality of second-order classifiers are trained for a respective variety of crop, and wherein the second-order classifier is trained for the specific variety of the crop in order to estimate the portion of the at least one of the broken grain or the non-grain components; and
estimate, using the selected second-order classifier, the portion of the at least one of the broken grain or the non-grain components.
