CSM-Net: A Multi-Task Colorectal Cancer Analysis Framework

Colorectal cancer is the second leading cause of cancer mortality before 2020, in this paper, we propose a simple yet efficient anchor-free instance segmentation framework, Colorectal Spatial Mask Network, aiming at jointly detecting and segmenting the tumor region in colorectal cancer MRI image series. we add a novel spatial attention-guided mask branch to anchor-free one stage object detector into the framework with the same way in Mask R-CNN. In addition, we also employ an improved network VoVNetV2 as the new backbone network. After comparison with the state-of-the-arts methods, the results of experiments reveal that our framework can get well balance between speed and accuracy.
