Wormhole Chestnuts Identification Based On Digital Image Processing Technology

The loss of chestnuts after picking up in china can account for 35%$\sim$50% of the total production. Eaten by worms is one of the important reasons for the loss, which seriously affects the overall quality of chestnut. Chestnuts eaten by worms have wormholes on the nuts, the shapes and sizes of these wormholes are different, which brings much difficulties to the quality identification of chestnuts. At present, the main way to identify worm-eaten chestnuts is to observe and pick them out by human beings. The recognition results are greatly affected by the subjective factors of human, which also has problems such as low accuracy and slow speed. Image recognition technology has been widely used in the detection of agricultural products, mainly focusing on grains and fruits, but the application and research in nuts such as chestnuts are relatively small.
