Periodontal disease image classification method and system based on transfer learning

The invention discloses a periodontal disease image classification method and system based on transfer learning. The method comprises the steps of recognition and screening of periodontal images of a patient, preprocessing of the periodontal images and data set making, acquisition of a pre-training model, and deep model training and updating based on transfer learning. The method comprises the following steps: firstly, acquiring a patient photo sequence actually shot by a hospital, identifying a periodontal front photo of a patient from the patient photo sequence, and preprocessing the identified data; and then, based on a transfer learning method, training and fine tuning are performed on the pre-training model by using periodontal data, and finally a prediction model with generalization is obtained. According to the method, a transfer learning method is utilized, so that the deep model can still achieve good classification accuracy on a small amount of data, the difficulty of data collection is reduced, and
