Selective Synthetic Augmentation with Quality Assurance

no code implementations9 Dec 2019 Yuan Xue, Jiarong Ye, Rodney Long, Sameer Antani, Zhiyun Xue, Xiaolei Huang

To mitigate these issues, we investigate a novel data augmentation pipeline that selectively adds new synthetic images generated by conditional Adversarial Networks (cGANs), rather than extending directly the training set with synthetic images.

SegAN: Adversarial Network with Multi-scale $L_1$ Loss for Medical Image Segmentation

2 code implementations6 Jun 2017 Yuan Xue, Tao Xu, Han Zhang, Rodney Long, Xiaolei Huang

Extensive experimental results demonstrate the effectiveness of the proposed SegAN with multi-scale loss: on BRATS 2013 SegAN gives performance comparable to the state-of-the-art for whole tumor and tumor core segmentation while achieves better precision and sensitivity for Gd-enhance tumor core segmentation; on BRATS 2015 SegAN achieves better performance than the state-of-the-art in both dice score and precision.
