Hazelnut is one of the most important agricultural products of Turkey, the largest producer of hazelnuts in the world. The kernel of the hazelnut is a major ingredient of chocolate industry after its shell and skin is removed. Hazelnuts with partial skin after the skinning process are rejected by the chocolate industry. Manufacturers have hazelnuts inspected by workers after the skin removal. An automated image processing and classification system based on Fuzzy Logic to identify partial skinned hazelnuts on a conveyor belt is proposed in this paper.
