Balanced Phase Field model for Active Surfaces
For researchers in image segmentation and active contours, this provides a method to avoid shrinkage artifacts, but it is an incremental extension of prior work.
This work generalizes a balanced phase field model for active surfaces to eliminate curvature-dependent shrinking of the zero level set while maintaining smooth interfaces. The model demonstrates strong shape preservation without interfering with active contour models.
In this paper we present a balanced phase field model for active surfaces. This work is devoted to the generalization of the Balanced Phase Field Model for Active Contours devised to eliminate the often undesirable curvature-dependent shrinking of the zero level set while maintaining the smooth interface necessary to calculate the fundamental geometric quantities of the represented contour. As its antecedent work, the proposed model extends the Ginzburg-Landau phase field energy with a higher order smoothness term. The relative weights are determined with the analysis of the level set motion in a curvilinear system adapted to the zero level set. The proposed model exhibits strong shape maintaining capability without significant interference with the active (e.g. a segmentation) model.
