A novel combined level set model for automatic MR image segmentation
Current Directions in Biomedical Engineering, 2020 Medical image processing comes along with object segmentation, which is one of the most important tasks in that field. Nevertheless, noise and intensity inhomogeneity in magnetic resonance images challenge the segmentation procedure. The level set method

Parametric Level Set Methods for Inverse Problems [PDF]
SIAM Journal on Imaging Sciences, 2011 In this paper, a parametric level set method for reconstruction of obstacles in general inverse problems is considered. General evolution equations for the reconstruction of unknown obstacles are derived in terms of the underlying level set parameters.
