Aiming at the existing defects of sanitary ceramics in the production, we proposed a method of defect image recognition based on color features of sanitary ceramics. The method established the defect feature library for sanitary ceramics defect image detection, it can fast recognize sanitary ceramics glaze missing image. Through a large number of scientific experiments, defect feature library was influenced by light and background factors. The method of image recognition of sanitary ceramics missing, has quick exactly speed and high precision. This paper provides a new idea for the detection of sanitary ceramic products.
