Smoothing with Active Surfaces: A Multiphase Level Set Approach

In this paper, we propose to use an active contour method to attract active surfaces towards non-smoothed segmentation masks. To achieve this task, we introduce a new region-based term for active contour segmentation in the multiphase level set framework. This term attracts evolving curves to reference contours while being constrained by rigidity terms. This technique considerably reduces flickering on the boundaries of the segmentation masks
