FEATURE RELEVANCE ASSESSMENT OF MULTISPECTRAL AIRBORNE LIDAR DATA FOR TREE SPECIES CLASSIFICATION
Multispectral Lidar 3D point clouds Intensity Tree Species Classification Feature Analysis
2018/5/11
The presented experiment investigates the potential of Multispectral Laser Scanning (MLS) point clouds for single tree species classification. The basic idea is to simulate a MLS sensor by combining t...
USABILITY OF A SUNLIT - SHADED AREA SEPARATION IN INDIVIDUAL TREE SPECIES CLASSIFICATION
Aerial Classification Forestry Fusion Imagery Multispectral
2016/2/29
Individual tree species classification can be done using Light Detection and Ranging (LIDAR) and aerial multichannel images
simultaneously. LIDAR is typically used to derive shape features and aeria...
USING INDIVIDUAL TREE CROWN APPROACH FOR FOREST VOLUME EXTRACTION WITH AERIAL IMAGES AND LASER POINT CLOUDS
Individual Tree Crown (ITC) Laser scanning Tree height Aerial imagery Segmentation
2015/8/13
The objective of this paper is to improve the cost-effectiveness (accuracy of estimates versus applied costs) of present ITC
(Individual Tree Crown) approaches which are based on 1) aerial imagery or...
On $p$-adic Gibbs Measures for Hard Core Model on a Cayley Tree
Cayley trees hard core interaction Gibbs measures translation invariant measures periodic measures
2011/9/20
Abstract: In this paper we consider a nearest-neighbor $p$-adic hard core (HC) model, with fugacity $\lambda$, on a homogeneous Cayley tree of order $k$ (with $k + 1$ neighbors). We focus on $p$-adic ...
Framework for discrete-time quantum walks and a symmetric walk on a binary tree
discrete-time quantum walks symmetric walk Framework Quantum Physics
2011/10/9
Abstract: We formulate a framework for discrete-time quantum walks, motivated by classical random walks with memory. We present a specific representation of the classical walk with memory 2 on which t...
Feynman's Tree Theorem and Loop-Tree Dualities
Feynman's Tree Theorem Loop-Tree Dualities
2010/12/24
We discuss the duality theorem, which provides a relation between loop integrals and phase space integrals. We rederive the duality relation for the one-loop case and extend it to two and higher-order...
In this paper, we study the tree amplitudes with gluons coupled to gravitons. We first study the relations among the mixed amplitudes. With BCFW on-shell recursion relation, we will show the color-ord...
Efficient Tree-Amplitudes in N=4: Automatic BCFW Recursion in Mathematica
Efficient Tree-Amplitudes in N=4 Automatic BCFW Recursion Mathematica
2010/12/27
We describe an efficient implementation of the BCFW recursion relations for tree-amplitudes in N=4 super Yang-Mills, which can generate analytic formulae for general N^kMHV colour-ordered helicity-amp...
Note on Bonus Relations for N=8 Supergravity Tree Amplitudes
Bonus Relations N=8 Supergravity Tree Amplitudes
2010/12/24
We study the application of non-trivial relations between gravity tree amplitudes, the bonus relations, to all tree-level amplitudes in N=8 supergravity. We show that the relations can be used to sim...

A RELATION BETWEEN THE MATCHING NUMBER AND LAPLACIAN SPECTRUM OF A TREE
Tree Laplacian spectrum matching numbe
2007/8/7
Let $T$ be a tree with matching number $\mu(T)$. In this paper we obtain thefollowing result: If $T$ has no perfect matchings, then $\mu(T)$ is a lower bound forthe number of nonzero Laplacian eigenva...
TREE CROWN DETERMINATION USING TERRESTRIAL IMAGING FOR LASER SCANNED INDIVIDUAL TREE RECOGNITION
Method Development Image Tree crown
2015/6/1
A method to measure tree crown dimensions is introduced in this article. The method is based on terrestrial images, which are
captured from two different directions. Image orientation is registered ...
