Morphing of Triangular Meshes in Shape Space [PDF]

, 2008
We present a novel approach to morph between two isometric poses of the same non-rigid object given as triangular meshes. We model the morphs as linear interpolations in a suitable shape space $\mathcal{S}$.

A Low-Cost, Repeatable Method for 3D Particle Analysis with SfM Photogrammetry

Geosciences, 2023
The characterisation of particle shape is an important analysis in the field of sedimentary geology. At finer scales, it is key for understanding sediment transport while at coarser scales, such as boulders, it is vital for coastal protection.

3D shape segmentation via shape fully convolutional networks [PDF]

Computers & Graphics, 2018
We desgin a novel fully convolutional network architecture for shapes, denoted by Shape Fully Convolutional Networks (SFCN). 3D shapes are represented as graph structures in the SFCN architecture, based on novel graph convolution and pooling operations, which are similar to convolution and pooling operations used on images. Meanwhile, to build our SFCN

Camera Motion Agnostic Method for Estimating 3D Human Poses

Sensors, 2022
Although the performance of 3D human pose and shape estimation methods has improved considerably in recent years, existing approaches typically generate 3D poses defined in a camera or human-centered coordinate system. This makes it difficult to estimate

Applying mesh conformation on shape analysis with missing data [PDF]

, 2004
A mesh conformation approach that makes use of deformable generic meshes has been applied to establishing correspondences between 3D shapes with missing data.

Microstructural evolution and mechanical performance of nano-Nb-modified AlSi10Mg alloy fabricated by laser powder bed fusion

Journal of Materials Research and Technology
In this study, nano-Nb-modified AlSi10Mg composites were fabricated using laser powder bed fusion (LPBF). The effects of Nb addition on the microstructure and mechanical properties of the AlSi10Mg alloy were systematically investigated. Compared with the

Medial Axis for the Cortical Representation of 3D Shape

i-Perception, 2012
Representation of shape is a fundamental problem in vision science. Neurophysiological studies of macaque have reported that neurons in the primary visual cortex (V1) respond to Medial Axis (MA) of 2D surface, and that those in higher cortex (IT) respond

Single-Shot 3D Multi-Person Shape Reconstruction from a Single RGB Image

Entropy, 2020
Although the performance of the 3D human shape reconstruction method has improved considerably in recent years, most methods focus on a single person, reconstruct a root-relative 3D shape, and rely on ground-truth information about the absolute depth to ...

The extraction of depth structure from shading and texture in the macaque brain. [PDF]

PLoS ONE, 2009
We used contrast-agent enhanced functional magnetic resonance imaging (fMRI) in the alert monkey to map the cortical regions involved in the extraction of 3D shape from the monocular static cues, texture and shading.

HUMANNET—A Two-Tiered Deep Neural Network Architecture for Self-Occluding Humanoid Pose Reconstruction

Sensors, 2021
Majority of current research focuses on a single static object reconstruction from a given pointcloud. However, the existing approaches are not applicable to real world applications such as dynamic and morphing scene reconstruction.
