Joint Vessel Segmentation And Deformable Registration On Multi-Modal Retinal Images Based On Style Transfer
2019 IEEE INTERNATIONAL CONFERENCE ON IMAGE PROCESSING (ICIP)(2019)
摘要
In multi-modal retinal image registration task, there are two major challenges, i.e., poor performance in finding correspondence due to inconsistent features, and lack of labeled data for training learningbased models. In this paper, we propose a joint vessel segmentation and deformable registration model based on CNN for this task, built under the framework of weakly supervised style transfer learning and perceptual loss. In vessel segmentation, a style loss guides the model to generate segmentation maps that look authentic, and helps transform images of different modalities into consistent representations. In deformable registration, a content loss helps find dense correspondence for multi-modal images based on their consistent representations, and improves the segmentation results simultaneously. Experiment results show that our model has better performance than other deformable registration methods in both quantitative and visual evaluations, and the segmentation results also help the rigid transformation.
