Abstract: 【Aim】 The spider mites are the main pests of many crops. Traditional recognition methods for spider mites relied on the naked eyes, which wasted a lot of time and energy. In order to study the fast automatic recognition method for spider mites, a method using computer image analysis algorithm was developed. 【Methods】 The method based on the K-means clustering algorithm realized the segmentation and recognition of the spider mite images which were obtained from fields. 【Results】 In contrast to the traditional RGB color segmentation method, the K-means clustering algorithm method was able to separate the images of spider mites from leaf background effectively. The average recognition time based on the K-means clustering algorithm was 3.56 s, and the recognition accuracy was 93.95%. The recognition time (T) increased as the pixels of tested image (Pi) increased. 【Conclusion】 The method can be applied to the segmentation and recognition of spider mite images.
