Computation of Breast Ptosis from 3D Scans of Torso
… and evaluated the utility of three-dimensional (3D) features such as surface curvature, coronal projection and surface normal for the assessment of breast ptosis using 3D scans of the torso. Experimental results suggest that 3D features are successful for objectively categorizing breast ptosis …

Analyzing the Consistency of Scoring Porotic Hyperostosis From 3D Scans
<p>The use of 3D scans is becoming more and more common in the field of bioarchaeology. They alleviate the need to travel, allow for larger sample sizes, and can help preserve bones with pathologies on them which make them more fragile. Though there are major benefits with using 3D scanning of …

3 - DJ : sampling as design
3D Sampling is introduced as a new spatial craft that can be applied to architectural design, akin to how sampling is applied in the field of electronic music. Through the development of 3-DJ, a prototype design software, I propose a design methodology that enables a designer to evaluate, remix, …

Intra-Oral Three Dimensional Scanning for Assessment of Surgical Outcome in Patients with Unilateral Cleft Lip and Palate
… be scanned to create indirect three dimensional (3D) digital models and dental arches can be scanned directly using an intra-oral 3D scanner. The latter technique eliminates the need for impression taking but has not previously been investigated in cleft care.Aims: This prospective study aimed to …

GAUSSIAN PROCESSES FOR 3D SHAPE MODELLING OF NOISY AND INCOMPLETE DATA. AN APPLICATION TO HUMAN EARS RECONSTRUCTION
Mathematical modelling of 3D shapes is a requirement in a vast and increasing number of applications, especially when it comes to the human shape. Despite being an active branch of research, with many proposed solutions, some settings remain particularly challenging. An example of such an open …

Laser Surface Texturing To Create Biomimetic Surface Topographies For Marine Antifouling Efficacy Testing
… microscope (GFM) was used to investigate 3D scans of the surface topography of shells of bivalve and crab species, to provide bio-inspiration for the design of the surfaces created in this research. It was found that the micro-topography pattern limits the attachment of the biofilm to the …

3D Scan Campaign Classification with Representative Training Scan Selection
… has been shown to effectively classify points in 3D scans, and can accelerate manual tasks like the removal of unwanted points from cultural heritage scans. However, a classifier’s performance depends on which classifier and feature set is used, and choosing these is difficult since previous …

3D Deep Learning Segmentation for Fiber Break Analysis of Carbon Fiber Reinforced Polymer Tomograms
… of CFRPs under stress, enabling real-time 3D observation of the material’s failure. Due to the data-rich nature of the 3D scans at each time step, such experiments can result in thousands of 2D images per scan and multiple scans at different time- or loading-steps per test. This accumulates …

The mechanical and magnetic behaviour of sintered fibre networks and their suitability for a therapeutic, biomedical application
… methods:** To achieve the described objectives, 3D scans of sintered, cube-shaped fibre network samples made from AISI 316L or 444 stainless steel were acquired by means of computed tomography. Based on the finite element method and beam theory, the extracted network geometries were run as …

Learning of Multi-Dimensional, Multi-Modal Features for Robotic Grasping
… and with other agents. To this end, we present a 3D object model for autonomous, visuomotor interaction. The model represents grasping strategies along with visual features that predict their applicability. It provides a robot with the ability to compute grasp parameters from visual observations. …

Investigation of Photographic and Digital Methods for Odontological Comparison to aid with Human Identification
… method using 2D photographs of a smile and 3D dental models in dental identification. The application of 3D imaging has not been explored or utilised to its full potential in forensic dental identification. Hence, a study was designed with an aim to explore novel odontological methods by …
