NeoUNet: Towards accurate colon polyp segmentation and neoplasm detection [PDF]
arXiv, 2021 Automatic polyp segmentation has proven to be immensely helpful for endoscopy procedures, reducing the missing rate of adenoma detection for endoscopists while increasing efficiency. However, classifying a polyp as being neoplasm or not and segmenting it at the pixel level is still a challenging task for doctors to perform in a limited time.

Machine learning-based colon deformation estimation method for colonoscope tracking [PDF]
SPIE Medical Imaging 2018: Image-Guided Procedures, Robotic
Interventions, and Modeling, 2018 This paper presents a colon deformation estimation method, which can be used to estimate colon deformations during colonoscope insertions. Colonoscope tracking or navigation system that navigates a physician to polyp positions during a colonoscope insertion is required to reduce complications such as colon perforation.
