In order to improve the identification accuracy of fuzzy support vector machine for chalky rice, this paper puts forward a fuzzy support vector machine method based on fuzzy K nearest-neighbor. This method firstly gets a sample center by calculating sample mean aimed at every class sample; and then it calculates the initial membership of sample by calculating the distance between sample and center; finally, it calculates K neighbor points of each sample, calculates the membership of sample according to the fuzzy K neighbor method, and integrates the initial membership with fuzzy K neighbor membership at a certain proportion, to get the ultimate membership values of samples. Combined with image detection problems of rice, verify the validity of this method. Experiments show that this method not only can improve the accuracy of identification but also can improve its speed, with a better result than common fuzzy support vector machine.
