In this talk we introduce new variational methods for two-phase segmentation, focussing on medical imaging. The approaches we discuss concern the effective incorporation of user interactivity to segmentation and contouring, with respect to convex relaxation formulations and minimal path methods. We also present associated applications, such as organ contouring for radiotherapy planning and volume computation of abdominal aortic aneurysms, considering examples from multiple modalities in both 2D and 3D.
This presentation is part of Minisymposium “MS43 - Variational Image Segmentation: Methods and Applications”
