摘要:

训练数据是设计医学图像分析算法的关键组成部分,在许多情况下,它是实现良好结果的主要瓶颈。图像生成的最新进展已经使得能够使用合成数据来训练基于神经网络的解决方案。生成新样本的一个关键因素是控制重要的外观特征,并有可能生成具有不同变体的特定类别的新样本。在这项工作中,我们建议的合成新的数据混合类指定和未指定的表示不同的因素在训练数据。我们对CT中肝脏病变分类的实验显示,与基线训练方案相比,准确率平均提高了7.4%。

英文摘要:

Training data is the key component in designing algorithms for medical image analysis and in many cases it is the main bottleneck in achieving good results. Recent progress in image generation has enabled the training of neural network based solutions using synthetic data. A key factor in the generation of new samples is controlling the important appearance features and potentially being able to generate a new sample of a specific class with different variants. In this work we suggest the synthesis of new data by mixing the class specified and unspecified representation of different factors in the training data. Our experiments on liver lesion classification in CT show an average improvement of 7.4% in accuracy over the baseline training scheme.
