摘要:

X射线图像增强以及许多其他医学图像处理应用需要将图像分割为骨骼、软组织和开放射束区域。我们应用一个机器学习的方法来解决这个问题,提出了一个端到端的解决方案,导致强大和有效的推理。由于医疗机构通常没有资源来处理和标记神经网络训练所需的大量X射线图像,我们为小型数据集设计了一个端到端解决方案,同时实现了最先进的结果。我们的实现产生了92%的整体准确度,F1得分为0.92,AUC为0.98,超过了经典的图像处理技术,如聚类和基于熵的方法,同时提高了现有的神经网络的输出用于在非医疗背景下的分割。用于该项目的代码可在线获得。

英文摘要:

X-Ray image enhancement, along with many other medical image processing applications, requires the segmentation of images into bone, soft tissue, and open beam regions. We apply a machine learning approach to this problem, presenting an end-to-end solution which results in robust and efficient inference. Since medical institutions frequently do not have the resources to process and label the large quantity of X-Ray images usually needed for neural network training, we design an end-to-end solution for small datasets, while achieving state-of-the-art results. Our implementation produces an overall accuracy of 92%, F1 score of 0.92, and an AUC of 0.98, surpassing classical image processing techniques, such as clustering and entropy based methods, while improving upon the output of existing neural networks used for segmentation in non-medical contexts. The code used for this project is available online.
