Segmentation of the 3D printed mirror image auricular model to ease sculpture of the costal cartilages in total auricular aesthetic reconstruction

Asian Journal of Surgery, 2023
Background: Recently, three-dimensional (3D) models have been used more frequently than the traditional two-dimensional (2D) models as an intraoperative guide to ease sculpture of costal cartilages in total auricular aesthetic reconstruction in cases of ...

A survey on surface reconstruction based on 3D Gaussian splatting [PDF]

PeerJ Computer Science
Surface reconstruction is a foundational topic in computer graphics and has gained substantial research interest in recent years. With the emergence of advanced neural radiance fields (NeRFs) and 3D Gaussian splatting (3D GS), numerous innovative many ...

Neural 3D reconstruction from sparse views using geometric priors

Computational Visual Media, 2023
Sparse view 3D reconstruction has attracted increasing attention with the development of neural implicit 3D representation. Existing methods usually only make use of 2D views, requiring a dense set of input views for accurate 3D reconstruction.

Microtia deformity correction with three-dimensional and two-dimensional templates: A pathway for effective ear reconstruction

Journal of Clinical and Scientific Research, 2021
Expression of anatomical landmarks of the ear results in the success of ear reconstruction in microtia. Ear reconstruction in India is routinely done with a two-dimensional (2D) template by tracing the contralateral ear with an X-ray sheet.

Approximate Message Passing in Coded Aperture Snapshot Spectral Imaging [PDF]

, 2015
We consider a compressive hyperspectral imaging reconstruction problem, where three-dimensional spatio-spectral information about a scene is sensed by a coded aperture snapshot spectral imager (CASSI).

MeshLifter: Weakly Supervised Approach for 3D Human Mesh Reconstruction from a Single 2D Pose Based on Loop Structure

Sensors, 2020
In this paper, we address the problem of 3D human mesh reconstruction from a single 2D human pose based on deep learning. We propose MeshLifter, a network that estimates a 3D human mesh from an input 2D human pose.

Application of three-dimensional reconstruction with a Hisense computer-assisted system in upper pancreatic lymph node dissection during laparoscopic-assisted radical gastrectomy

Asian Journal of Surgery, 2021
Background/objective: To investigate the feasibility of three-dimensional (3D) reconstruction with an interactive Hisense computer-assisted system (CAS) for preoperative planning and intraoperative guidance during laparoscopic-assisted upper pancreatic ...

A sketching interface for 3D modeling of polyhedron [PDF]

, 2006
We present an intuitive and interactive freehand sketching interface for 3D polyhedrons reconstruction. The interface mimics sketching with pencil on paper and takes freehand sketches as input directly.

GANana: Unsupervised Domain Adaptation for Volumetric Regression of Fruit

Plant Phenomics, 2021
3D reconstruction of fruit is important as a key component of fruit grading and an important part of many size estimation pipelines. Like many computer vision challenges, the 3D reconstruction task suffers from a lack of readily available training data ...
