This module discusses several algorithms that calculate various geometric properties, mostly based on only two operations described below: cross product and arctangent.
This book is about 3D math, the study of the mathematics behind the geometry of a 3D world. 3D math is related to computational geometry, which deals with solving geometric problems algorithmically. 3D math and computational geometry have applicatio
This paper presents Griffin, a scheme of geometric routing on flat names to conduct massive content distribution andretrieval. A tree-based metric space T is proposed according to the concept of hierarchical division of symbol space. In Griffin, the
A new paradigm of scalable routing for ICN is to combine a geometric routing scheme with a Distributed Hash Table. However, for most routing schemes in this paradigm, when a node joins or leaves, large numbers of nodes, even the whole topology, need
Most of the histogram-based watermarking methods focused on the geometric invariance feature more while paying less attention to the robustness to some common image processing attacks like JPEG compression. In this paper, we propose a new histogram m
In recent years, geometry-based image and video processing methods have aroused significant interest. This paper considers progress from four aspects: geometric characteristics and shape, geometric transformations, embedded geometric structure, and d
The investigation of novel signal processing tools is one of the hottest research topics in modern signal processing community. Among them, the algebraic and geometric signal processing methods are shown to be one of the most powerful tools for the r
This paper proposes a Depth from Defocus (DFD) model based on geometric constraints. The two measured defocused images match with each other with this method incl
The evolutions of polarization and orbital angular momentum (OAM) states of light in helically twisted birefringent photonic crystal fibers (TB-PCFs) are analyzed. It is shown that a circular polarization (CP) component (
