ETRI Journal, 2021 We propose an efficient method for synthesizing mesh-based realistic computer-generated hologram (CGH). In a previous nonanalytic mesh-based CGH synthesis, the angular spectrum of the two-dimensional (2D) plane is calculated using the fast Fourier ...

Perceptual Quality and Visual Experience Analysis for Polygon Mesh on Different Display Devices
IEEE Access, 2018 Polygon mesh models have been widely used in various areas due to its high degree of verisimilitude and interactivity. Since the mesh models usually undergo various phases of signal processing for the purpose of storage, simplification, transmission, and

A Class of Refinement Schemes With Two Shape Control Parameters
IEEE Access, 2020 A subdivision scheme defines a smooth curve or surface as the limit of a sequence of successive refinements of given polygon or mesh. These schemes take polygons or meshes as inputs and produce smooth curves or surfaces as outputs. In this paper, a class

Consistently Orienting Facets in Polygon Meshes by Minimizing the Dirichlet Energy of Generalized Winding Numbers [PDF]
, 2014 Jacobson et al. [JKSH13] hypothesized that the local coherency of the generalized winding number function could be used to correctly determine consistent facet orientations in polygon meshes.

Creating Simplified 3D Models with High Quality Textures [PDF]
, 2015 This paper presents an extension to the KinectFusion algorithm which allows creating simplified 3D models with high quality RGB textures. This is achieved through (i) creating model textures using images from an HD RGB camera that is calibrated with ...

A STEGENOGRAPHY IN 3D MESH BY REARRANGING THE ORDER OF VERTEX PRESENTATION
Tạp chí Khoa học Đại học Đà Lạt, 2013 This paper proposes a method of data hiding approach on 3D mesh objects in the representation domain by rearranging the order of the vertices based on a secret key string (a list vertex that was previously traversed as highly secret).

ALIGNMENT OF HYPERSPECTRAL IMAGERY AND FULL-WAVEFORM LIDAR DATA FOR VISUALISATION AND CLASSIFICATION PURPOSES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 The overarching aim of this paper is to enhance the visualisations and classifications of airborne remote sensing data for remote forest surveys. A new open source tool is presented for aligning hyperspectral and full-waveform LiDAR data.

Progressive refinement rendering of implicit surfaces [PDF]
, 2007 The visualisation of implicit surfaces can be an inefficient task when such surfaces are complex and highly detailed. Visualising a surface by first converting it to a polygon mesh may lead to an excessive polygon count.
