Level Sets Guided by SoDEF-Fitting Energy for River Channel Detection in SAR Images
Remote Sensing, 2023 To achieve river channel detection in SAR (synthetic aperture radar) images, we developed a level-set-based model (LSBM) guided by a designed data-fitting energy which is called the SoDEF (sum of dual exponential functions)-fitting energy.

Level Sets of Weak-Morse Functions for Triangular Mesh Slicing
Mathematics, 2020 In the context of CAD CAM CAE (Computer-Aided Design, Manufacturing and Engineering) and Additive Manufacturing, the computation of level sets of closed 2-manifold triangular meshes (mesh slicing) is relevant for the generation of 3D printing patterns ...

(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 ...

Multi-Resolution Texture-Based 3D Level Set Segmentation
IEEE Access, 2020 This article presents a novel three-dimensional level set method for the segmentation of textured volumes. The algorithm combines sparse and multi-resolution schemes to speed up computations and utilise the multi-scale nature of extracted texture ...

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 estimation and Vorob'ev expectation of random compact sets [PDF]
, 2011 The issue of a "mean shape" of a random set $X$ often arises, in particular in image analysis and pattern detection. There is no canonical definition but one possible approach is the so-called Vorob'ev expectation $\E_V(X)$, which is closely linked to ...

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.

Setting school‐level outcome standards [PDF]
Medical Education, 2006 Background To establish international standards for medical schools, an appropriate panel of experts must decide on performance standards. A pilot test of such standards was set in the context of a multidimensional (multiple‐choice question examination, objective structured clinical examination, faculty ...
