Some comments on level sets of fuzzy sets [PDF]

open access: yes2008 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

A fully coupled level set-based topology optimization of flexible components in multibody systems

open access: yes, 2023
A fully coupled level set-based topology optimization of flexible components in multibody systems is considered. Thereby, using the floating frame of reference approach, the flexible components are efficiently modeled and incorporated in multibody ...

A new ghost cell/level set method for moving boundary problems:application to tumor growth [PDF]

open access: yes, 2008
In this paper, we present a ghost cell/level set method for the evolution of interfaces whose normal velocity depend upon the solutions of linear and nonlinear quasi-steady reaction-diffusion equations with curvature-dependent boundary conditions.

Quantitative Comparison of Deformable Models in Range Segmentation

open access: yesCybernetics and Information Technologies, 2015
In this paper we segment range images by applying three deformable models (the classical Active Contour, the adaptive active contour and the Level Set method). These three methods are used to segment images with planar and curved surface scenes. Then the

An efficient similarity-based level set model for medical image segmentation

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
It is usually difficult to correctly segment medical images with intensity inhomogeneity, which is of great significance in understanding of medical images. The local image intensity features play a vital role in accurately segmenting medical images with

A fully automated approach to prostate biopsy segmentation based on level-set and mean filtering

open access: yesJournal of Pathology Informatics, 2011
With modern automated microscopes and digital cameras, pathologists no longer have to examine samples looking through microscope binoculars. Instead, the slide is digitized to an image, which can then be examined on a screen. This creates the possibility

Confidence sets for a level set in linear regression [PDF]

open access: yesStatistics in Medicine
Regression modeling is the workhorse of statistics and there is a vast literature on estimation of the regression function. It has been realized in recent years that in regression analysis the ultimate aim may be the estimation of a level set of the regression function, ie, the set of covariate values for which the regression function exceeds a ...
