Confidence regions for level sets

This paper discusses a universal approach to the construction of confidence regions for level sets {h(x) ≥ 0} ⊂ Rd of a function h of interest. The proposed construction is based on a plug-in estimate of the level sets using an appropriate estimate �hn of h. The approach provides finite sample upper and lower confidence limits. This leads to generic conditions under which the constructed confid...

Object Contour Tracking Using Level Sets

High level vision tasks (recognition, understanding, etc.) for video processing require tracking of the complete contour of the objects. In general, objects undergo non-rigid deformations, which limit the applicability of using motion models (e.g. affine, projective) that impose rigidity constraints on the objects. In this paper, we propose a contour tracking algorithm for video captured using ...

How Reliable Are They?

We studied the frequency of malfunction, variability in rate of nebulization, and effect of this variability on aerosol particle size of eight disposable jet nebulizer models produced by six manufacturers. Four of eight models showed visual signs of malfunction, including spraying of large, individually visible droplets, leaking of nebulizer solution, and air leaks that completely prevented neb...

Sparse Finite Elements for Geodesic Contours with Level-Sets

Level-set methods have been shown to be an effective way to solve optimisation problems that involve closed curves. They are well known for their capacity to deal with flexible topology and do not require manual initialisation. Computational complexity has previously been addressed by using banded algorithms which restrict computation to the vicinity of the zero set of the level-set function. S...

Seventy FDG-PET/CT cases in which nuclear medicine physicians suspected lymphoma: How reliable are we?

Objective(s): To validate the reliability of nuclear medicine physicians in diagnosing lymphoma using positron emission tomography/computed tomography using 2-deoxy-2-[18F]fluoro-D-glucose (FDG-PET/CT) and to determine findings that reliably suggest lymphoma.Methods: Seventy patients suspected of having lymphoma using FDG-PET/CT were enrolled in this retrospective study. Two nuclear medicine ph...
