Query: Pathological Retinal Region Segmentation From OCT Images Using Geometric
  Relation Based Augmentation   Medical image segmentation is an important task for computer aided diagnosis.
Pixelwise manual annotations of large datasets require high expertise and is
time consuming. Conventional data augmentations have limited benefit by not
fully representing the underlying distribution of the training set, thus
affecting model robustness when tested on images captured from different
sources. Prior work leverages synthetic images for data augmentation ignoring
the interleaved geometric relationship between different anatomical labels. We
propose improvements over previous GAN-based medical image synthesis methods by
jointly encoding the intrinsic relationship of geometry and shape. Latent space
variable sampling results in diverse generated images from a base image and
improves robustness. Given those augmented images generated by our method, we
train the segmentation network to enhance the segmentation performance of
retinal optical coherence tomography (OCT) images. The proposed method
outperforms state-of-the-art segmentation methods on the public RETOUCH dataset
having images captured from different acquisition procedures. Ablation studies
and visual analysis also demonstrate benefits of integrating geometry and
diversity.
