3D model-based pose estimation of rigid objects from a single image for robotics
We address the problem of finding the best 3D pose for a known object, supported on a horizontal plane, in a cluttered scene in which the object is not significantly occluded. We assume that we are operating with RGB-D images and some information about the pose of the camera. We also assume that a …

Off-chip Communications Architectures For High Throughput Network Processors
… with direct, packet-based networks such as mesh, torus or k-ary n-cubes. We investigate multiple k-ary n-cube based interconnects and propose two variations of 2-ary 3-cube interconnect called the 3D-bus and 3D-mesh. All of the k-ary n-cube interconnects include multiple, highly efficient …

Single-View 3D Reconstruction of Animals
Humans have a remarkable ability to infer the 3D shape of objects from just a single image. Even for complex and non-rigid objects like people and animals, from just a single picture we can say much about its 3D shape, configuration and even the viewpoint that the photo was taken from. Today, the …

Distributed Displays for Discrete Integrated Circuit Electronics
… form into spatial 2D grid (structural) and 3D mesh (volumetric) displays, and overall reduce the cost and complexity of distributed display and computing systems.

Perceiving Shape from Surface Contours via Artificial Neural Networks
… at a simple collection of curves drawn upon a 3D surface, we can quickly glean general shape and curvature information; and such contours drawn on a 2D surface can give the illusion of curvature where there is none. Machines have no such visual intuition, and therefore are not particularly …

Efficient processor allocation strategies for mesh-connected multicomputers
… allocation strategies have been devised for mesh-connected multicomputers and these can be divided into two main categories: contiguous and non-contiguous. In contiguous allocation, jobs are allocated distinct contiguous processor sub-meshes for the duration of their execution. Such a …

User Leaving Detection Via MMwave Imaging
… uses a mmWave FMCW radar to capture the user’s 3D mesh and detects the leaving gesture from the 3D human mesh data with a hybrid PointNet-LSTM model. Based on explainable user point clouds, mmLock is more robust than existing gesture recognition systems which can only identify the raw signal …

Learning viewer-centered projections for 3D shape completion
… is to determine the effectiveness of different 3D shape representations in learning to generate volumetric shapes using deep neural networks. We propose to automatically reconstruct a 3D model from a single-view image of an object by synthesizing multiple depth images and inferring the volume …

Contributions to automatic meshing in the AMORE scheme
… of continuous bodies into connected meshes of triangles and quadrilaterals (in 2D; tetrahedrals [tet] and hexahedrals [hex] in 3D) elements. Besides the restrictions due to compatibility of adjacent elements, one primary concern regarding mesh generation is that of minimizing the …

A Computational Method for Flow Separation Detection and Control for Axial Compressor Airfoils
… GRAPE and TCGRID are used to generate 2D and 3D mesh around the airfoil, and, to analyze the flow, RVCQ3d and SWIFT are employed for 2D and 3D cases, respectively, to detect separation on the Suction Surface of the stator. The commercial CFD code Gambit is used to generate mesh around a 3D …

Point cloud alignment in arm reconstruction for lymphedema detection by iterating pairwise ICP
… used to scan a patient's arm in order to build a 3D mesh that can be used to extract not only the total volume of the arm but also the volume of specific segments. A special focus is given to the method of global registration of each camera's depth image, where camera positions are iteratively …

REVO: A flexible, volumetric approach to mesh construction
Meshes are used in a variety of applications to specify the three dimensional (3D) shapes of objects in simulated scenes. For example, a mesh can be used as an animal in an animation movie, a soldier in a video game, or a bulldozer in a simulation application. A straightforward way of creating a …
