Wheat Quality Recognition Based on Watershed Algorithm and Kernel Partial Least Squares

Wheat quality recognition is depended on its shape and color characteristics. Watershed algorithm often can be used to extract complete particles images from the wheat photos, and get their important characteristics. In this paper, Kernel PLS (KPLS) algorithm was used to build a model for wheat kernel classification. A 3-layer back propagation artificial neural network (ANN) was also used for the same data set. The results showed that feature extraction techniques based on high performance watershed algorithm was reliable and high-speed. Average classification accuracy of KPLS and ANN for test set reached 98.00% and 97.00%.
