A level set method for ductile fracture [PDF]
We utilize the shape derivative of the classical Griffith's energy in a level set method for the simulation of dynamic ductile fracture. The level set is defined in the undeformed configuration of the object, and its evolution is designed to represent a transition from undamaged to failed material.

A Variational Level Set Image Segmentation Method via Fractional Differentiation
To solve the issues with conventional level set segmentation algorithms, which are sensitive to the initial contours and less noise-resistant, a segmentation model based on the coupling of texture information and structural information is developed.

Some numerical aspects of the level set method
Many practical applications imply the solution of free boundary value problems. If the free boundary is complex and can change its topology, it will be hard to solve such problems numerically.

Deep level-set method for Stefan problems
We propose a level-set approach to characterize the region occupied by the solid in Stefan problems with and without surface tension, based on their recent probabilistic reformulation. The level-set function is parameterized by a feed-forward neural network, whose parameters are trained using the probabilistic formulation of the Stefan growth condition.

A Hybrid Semantic Segmentation Based on Level-Set Evolution Driven by Fully Convolutional Networks
Semantic segmentation network is one successful deep architecture for understanding key foregrounds. The fully convolutional networks (FCNs) can learn the regional masks by composing layered representations coarse-to-fine.
