主　　题：wear particles classifier morphological priors data augmentation deep residual network 

摘      要：Finding the correct category of wear particles is important to understand the tribological ***,manual identification is tedious and *** here propose an automatic morphological residual convolutional neural network(M-RCNN),exploiting the residual knowledge and morphological priors between various particle *** also employ data augmentation to prevent performance deterioration caused by the extremely imbalanced problem of class *** results indicate that our morphological priors are distinguishable and beneficial to largely boosting overall performance.M-RCNN demonstrates a much higher accuracy(0.940)than the deep residual network(0.845)and support vector machine(0.821).This work provides an effective solution for automatically identifying wear particles and can be a powerful tool to further analyze the failure mechanisms of artificial joints.
