Accuracy in scientific visualisation [PDF]

, 1999
Quite often, accuracy is a neglected issue in scientific visualization. Indeed, in most of the visualizations there are two wrong assumptions: first, that the data visualized is accurate. Second, that the visualization process is exempt from errors.

Wider Contours and Adaptive Contours [PDF]

, 2019
Contour integrals in the complex plane are the basis of effective numerical methods for computing matrix functions, such as the matrix exponential and the Mittag-Leffler function. These methods provide successful ways to solve partial differential equations, such as convection--diffusion models.

Effects of variability in manually contoured spinal cord masks on fMRI co-registration and interpretation

Frontiers in Neurology, 2022
Functional magnetic resonance imaging (fMRI) of the human spinal cord (SC) is a unique non-invasive method for characterizing neurovascular responses to stimuli.

Comparison of Manual and Semi-Automatic [18F]PSMA-1007 PET Based Contouring Techniques for Intraprostatic Tumor Delineation in Patients With Primary Prostate Cancer and Validation With Histopathology as Standard of Reference

Frontiers in Oncology, 2020
PurposeAccurate contouring of intraprostatic gross tumor volume (GTV) is pivotal for successful delivery of focal therapies and for biopsy guidance in patients with primary prostate cancer (PCa). Contouring of GTVs, using 18-Fluor labeled tracer prostate

Atlas-Based Shared-Boundary Deformable Multi-Surface Models through Multi-Material and Two-Manifold Dual Contouring

Information, 2023
This paper presents a multi-material dual “contouring” method used to convert a digital 3D voxel-based atlas of basal ganglia to a deformable discrete multi-surface model that supports surgical navigation for an intraoperative MRI-compatible surgical ...

Contour complexity and contour detection

Journal of Vision, 2015
Itis well-known that "smooth" chains of oriented elements-contours-are more easily detected amid background noise than more undulating (i.e., "less smooth") chains. Here, we develop a Bayesian framework for contour detection and show that it predicts that contour detection performance should decrease with the contour's complexity, quantified as the ...

Applications of Contouring [PDF]

SIAM Review, 2000
The paper is dedicated to several practical applications of the contouring problem. After a description of the contouring problem, an original application is described, respectively computing planar cuts and surface intersections. The computation of horizon lines is the subject of another part of the paper.

Body Contouring

, 2023
Body contouring surgery has evolved in the last few decades, influenced by three main aspects: cultural changes alongside social media and new concepts of beauty, the surgeon and their focus on achieving natural results, and the influence of new ...
