Augmented Lagrangian method for an Euler's elastica based segmentation model that promotes convex contours
Bae, Egil; Tai, Xue-Cheng; Wei, Zhu (2017)In this paper, we propose an image segmentation model where an L1 variant of the Euler's elastica energy is used as boundary regularization. An interesting feature of this model lies in its preference for convex segmentation ... -
Simplified energy landscape for modularity using total variation
Boyd, Zachary; Bae, Egil; Tai, Xue-Cheng; Bertozzi, Andrea L. (2018)Networks capture pairwise interactions between entities and are frequently used in applications such as social networks, food networks, and protein interaction networks, to name a few. Communities, cohesive groups of nodes, ...
