基于深度神经网络的尺桡骨远端图像语义分割

DRU Image Semantic Segmentation Using Deep Neural Networks

对尺桡骨远端图像进行语义分割可以提取出尺骨桡骨感兴趣区域(ROI),ROI提取对后期的辅助诊断分析非常重要。本文提出了一种基于深度全卷积神经网络的语义分割模型,并对尺桡骨远端图像进行像素级的语义分割。实验表明,该模型可以精准地从尺桡骨远端图像中分割尺骨、桡骨并识别其语义,并分析了几种典型网络结构对分割模型的影响作用。分割模型对尺骨的识别精度和召回率为97%,交并比(IoU)为95%;对桡骨识别精度为98.5%,召回率为98%,交并比(IoU)为96.6%。

Abstract Semantic segmentation of the distal radius and ulna images can extract the region of interest (ROI) for Ulnar radius, which counts a great deal for bone age recognition. In this work, we propose a fully convolutional network based model for semantic segmentation. Experimental results show that the proposed model can precisely segment the ulna and radius from distal radius and ulna images. We also discussed the influence of different network structures. For ulna, we get an accuracy of 97%, recall of 97%, IoU of 95%. For radius, we get an accuracy of 98.5%, recall of 98%, IoU of 96.6%.
