Multi-scale segmentation using deep graph cuts: Robust lung tumor delineation in MVCBCT
Xiaodong Wu, Zisha Zhong, John Michael Buatti, Junjie Bai · 2018
Deep networks have been used in a growing trend in medical image analysis with the remarkable progress in deep learning. In this paper, we formulate the multi-scale segmentation as a Markov Random Field (MRF) energy minimization problem in a deep network (graph), which can be efficiently and exactly solved by computing a minimum s-t cut in an appropriately constructed graph. The performance of the proposed method is assessed on the application of lung tumor segmentation in 38 mega-voltage cone-beam computed tomography datasets.
