Domain-Robust Mitotic Figure Detection with StyleGAN
share
We propose a new training scheme for domain generalization in mitotic figure detection. By considering the image variance due to different scanner types as different image styles, we have trained our detection network to be robust on scanner types. To expand the image variance, domain of training image is transferred into arbitrary domain. The proposed style transfer module generates different styled images from an input image with random code, eventually generating variously styled images. Our model with the proposed training scheme shows good performance on MIDOG Preliminary Test-Set containing scanners never seen before.
