Hybrid face recognition, using image (2D) and structural (3D) information, has explored the fusion of Nearest Neighbour classifiers. This paper examines the effectiveness of feature modelling for each individual modality, 2D and 3D. Furthermore, it is demonstrated that the fusion of feature modelling techniques for the 2D and 3D modalities yields performance improvements over the individual cla...

An algorithm for surface domain decomposition and grid generation for overset grids is described. A complex surface domain is covered by two types of grids: seam grids and block grids. Seam grids are grids used to wrap around surface crease lines and regions of high surface curvature. Block grids are grids that cover the remaining surface regions not occupied by the seam grids. The seam and blo...

Polygonal meshes are widely used to represent the shape of 3D objects and the generation of multi-resolution models has been a significant research topic in computer graphics. In this paper, we demonstrate how to generate multi-resolution models through 2D image processing techniques. The goal of generating multi-resolution models is accomplished by resizing the corresponding geometry images of...

In industrial assembly lines, seam sealing is a painting process used for making watertight seals or for preventing rusting. In the process, sealant is painted on seams located at the joints of pressed metal parts. We developed a sealing robot system that adjusts the sealing gun motion adaptively to the seam position sensed by a range sensor (a scanning laser rangefinder which senses profile ra...

Let Ω1 and Ω2 be strongly pseudoconvex domains in C and f : Ω1 → Ω2 an isometry for the Kobayashi or Carathéodory metrics. Suppose that f extends as a C map to Ω̄1. We then prove that f |∂Ω1 : ∂Ω1 → ∂Ω2 is a CR or anti-CR diffeomorphism. It follows that Ω1 and Ω2 must be biholomorphic or anti-biholomorphic. The main tool is a metric version of the Pinchuk rescaling technique.

SEAM is an enterprise architecture method that defines a visual language for modeling. Our goal is to provide formal semantics for SEAM. Model simulation, model comparison, and refinement verification are practical benefits we expect from this formalization. This paper complements the existing SEAM semantics by formalizing property-property relations. This formalization is based on the theory o...

Aiming to reduce the high mining stress observed in large-space roof structures during mechanized mining of thick coal seams, a control technique based on protective-seam mining is proposed. This technique was used to investigate the 8108 working face of the No. 3–5 thick coal seam of the Tashan mine located in the Datong area of Shanxi, China, by means of simulations and field measurements. Th...

ABSTRACT When changing height and width of image traditional techniques for image resizing are oblivious to the content of image. A simple operator seam carving is used for image and video retargeting. This seam carving operator is used for content aware image resizing to reduce or expand image size. According to seam carving method every object in the image must be scaled down proportionally. ...

Distortion prediction of a welded structure is an important way to improve work efficiency and ensure product quality during the fabrication process. Recently, widely used approaches for evaluating residual deformation include thermo-elastic-plastic finite element method (TEP-FEM) inherent strain (ISM). The former can accurately simulate entire welding process with excessive computational time,...

CAPjournal, No. 22, September 2017 Three-dimensional (3D) modelling is more than just good fun, it offers a new vehicle to represent and understand scientific data and gives experts and non-experts alike the ability to manipulate models and gain new perspectives on data. This article explores the use of 3D modelling and printing in astronomy and astronomy communication and looks at some of the ...
