CoRR, 2023 We present a new algorithm for image segmentation - Level-set KSVD. Level-set KSVD merges the methods of sparse dictionary learning for feature extraction and variational level-set method for image segmentation. Specifically, we use a generalization of the Chan-Vese functional with features learned by KSVD.

(Convex) Level Sets Integration [PDF]
Journal of Optimization Theory and Applications, 2015 The authors investigate the problem of recovering a pseudoconvex function from a multi-valued map that generates the normal cones to the (lower) level set of the function. This ``(convex) level set integration'' is a generalization of the classical problem of recovering (integrating) a differentiable function from its gradient with a given value in ...

Some Results on Single Valued Neutrosophic Hypergroup [PDF]
Neutrosophic Sets and Systems, 2020 We introduced the theory of Single valued neutrosophic hypergroup as the initial theory of single valued neutrosophic hyper algebra and also developed some results on single valued neutrosophic hypergroup.

Level sets regularization with application to optimization problems
Cubo, 2020 Given a coupling function $c$ and a non empty subset of $\R$, we define a closure operator. We are interested in extended real-valued functions whose sub-level sets are closed for this operator. Since this class of functions is closed under pointwise

Flower segmentation with level sets evolution controlled by colour, texture and shape features
Cogent Engineering, 2017 This work proposes a pre-informed Chan vese based level sets algorithm. Pre information includes objects colour, texture and shape fused features. The aim is to use this algorithm to segment flower images and extract meaningful features that will help is

A PDE Method to Segment Image Linear Objects with Application to Lens Distortion Removal
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2007 In this paper, we propose a partial differential equation based method to segment image objects, which have a given parametric shape based on energy functional.

Some comments on level sets of fuzzy sets [PDF]
2008 IEEE International Conference on Fuzzy Systems (IEEE World Congress on Computational Intelligence), 2008 This paper discusses level sets of functions from a set U into a set C with an order structure, for example a poset or a lattice. Such sets are prevalent in fuzzy set theory. We provide some general facts and then consider the particular case when C is the complete lattice of closed intervals in the unit interval [0,1]; that is, when the function is an
