Image-Based Multiresolution Implicit Object Modeling [PDF]
EURASIP Journal on Advances in Signal Processing, 2002 We discuss two image-based 3D modeling methods based on a multiresolution evolution of a volumetric function′s level set. In the former method, the role of the level set implosion is to fuse ("sew" and "stitch") together several partial ...

Evaluating Image-Based Interactive 3D Modeling Tools
IEEE AccessStructure from Motion (SfM) is a computer vision technique used to reconstruct three-dimensional (3D) structures from a series of two-dimensional (2D) images or video frames.

Image-based Model Completion [PDF]
Sixth International Conference on 3-D Digital Imaging and Modeling (3DIM 2007), 2007 Geometric models created from range sensors are usually incomplete. Considerable effort has been made to fix this problem, ranging from manual repairing to geometric interpolation. We propose using multi-view stereo to complete such models. Our approach is practical and convenient because when scanning and object or environment one usually takes ...

Image-based modelling of organogenesis [PDF]
Briefings in Bioinformatics, 2015 One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks - and how can they change as a result of mutations?

A Structured Cleaving Mesh for Bioheat Transfer Application
IEEE Open Journal of Engineering in Medicine and Biology, 2020 Goal: The thermoregulation mechanism is a complex system that executes vital processes in the human body. Various models have been proposed to simulate the thermoregulatory response of an adult human to environmental stimuli.

Frontiers in Cardiovascular Medicine, 2022 BackgroundCardiac CT (CCT) is well suited for a detailed analysis of heart structures due to its high spatial resolution, but in contrast to MRI and echocardiography, CCT does not allow an assessment of intracardiac flow.

Image-Based Model Updating [PDF]
Procedings of the British Machine Vision Conference 2002, 2002 This paper presents a novel image-based approach for updating the geometry of 3D models. The technique can cope with large-scale models, using a single imaging sensor to which an arbitrary motion is applied. Current approaches usually do not fully take advantage of strong prior information, often available in the form of an initial model.

Computed Tomography-Based Assessment of Transvalvular Pressure Gradient in Aortic Stenosis
Frontiers in Cardiovascular Medicine, 2021 Background: In patients with aortic stenosis, computed tomography (CT) provides important information about cardiovascular anatomy for treatment planning but is limited in determining relevant hemodynamic parameters such as the transvalvular pressure ...
