E$^2$Net: An Edge Enhanced Network for Accurate Liver and Tumor Segmentation on CT Scans [PDF]

arXiv, 2020
Developing an effective liver and liver tumor segmentation model from CT scans is very important for the success of liver cancer diagnosis, surgical planning and cancer treatment. In this work, we propose a two-stage framework for 2D liver and tumor segmentation.
