Filling holes in meshes using a mechanical model to simulate the curvature variation minimization [PDF]
, 2006 The presence of holes in a triangle mesh is classically ascribed to the de ciencies of the point cloud acquired from a physical object to be reverse engineered.

Explicit Analysis of Sheet Metal Forming Processes Using Solid-Shell Elements
Metals, 2021 To simulate sheet metal forming processes precisely, an in-house dynamic explicit code was developed to apply a new solid-shell element to sheet metal forming analyses, with a corotational coordinate system utilized to simplify the nonlinearity and to ...

Novel Low Cost 3D Surface Model Reconstruction System for Plant Phenotyping
Journal of Imaging, 2017 Accurate high-resolution three-dimensional (3D) models are essential for a non-invasive analysis of phenotypic characteristics of plants. Previous limitations in 3D computer vision algorithms have led to a reliance on volumetric methods or expensive ...

Patient-specific reconstruction of volumetric computed tomography images from a single projection view via deep learning [PDF]
Nature Biomedical Engineering, 2019 Tomographic imaging using penetrating waves generates cross-sectional views of the internal anatomy of a living subject. For artefact-free volumetric imaging, projection views from a large number of angular positions are required. Here we show that a deep-learning model trained to map projection radiographs of a patient to the corresponding 3D anatomy ...

Three-Dimensional Single Random Phase Encryption
SensorsIn this paper, we propose a new optical encryption technique that uses the single random phase mask. In conventional optical encryptions such as double random phase encryption (DRPE), two different random phase masks are required to encrypt the primary ...
