Abstract:

Confident learning plays an important role in the training of low-quality labeled data of medical images, but the current application of confident learning is based on the mean teacher model, and the possibility on other networks is not discussed. To solve this problem, a segmentation model based on confident learning and collaborative training is proposed in this paper. The model uses two different networks, encourages the output of the two networks to be consistent, and then compares the output of one network with the original low-quality label by using confident learning to modify the low-quality labeled data so as to provide an effective training reference. The proposed model has been compared on three different modal medical image datasets, and the experimental results show that the segmentation effect of the model is better than that of the existing confident learning model.

Key words: computer application, medical image segmentation, confident learning, collaborative training
