The process of deep learning algorithm system, which consists of the two algorithms Attention U-net and Inception-ResNet-V2. Imaging preprocessing was performed by zero padding, resize, histogram equalization, Min–Max normalization, and gamma correction. After segmentation of fractured vertebral body and background soft tissue anatomy by trained Attention U-net, post-processing of predicted segmentation (label) and patch extraction were performed. Final classification task was performed by Inception-ResNet-V2.
