【Abstract】 The external color feature of apples was extracted from the hue histograms using computer vision technology. With the advanced Genetic Algorithms, a three layer feed forward neural network system was established, which can realize on line automated judgment for maturity degree of apples. This method was proved to be robust, flexible , high speed as well as accurate.更多还原
