KERNEL FEATURE CROSS-CORRELATION FOR UNSUPERVISED QUANTIFICATION OF DAMAGE FROM WINDTHROW IN FORESTS
Feature matching Kernel normalized cross-correlation Forest Support Vector Machines
2016/11/23
In this study estimation of tree damage from a windthrow event using feature detection on RGB high resolution imagery is assessed. An accurate quantitative assessment of the damage in terms of volume ...
Cross-correlation of quality parameters of musts and wines enriched with lignans
hydroxymatairesinol (HMR) enrichment of must and wine correlations antioxidant activity total polyphenol concentration consumer acceptability
2016/2/23
Hydroxymatairesinol (HMR) is the main lignan found in spruce knots. This lignan has been used for enrichment of musts and wines. Quality parameters of these products have been studied for several year...
GRADIENT CROSS CORRELATION FOR SUB-PIXEL MATCHING
Correlation Matching Registration Fusion Multisensor
2015/12/31
Sub-pixel matching is one of the key components for image registration and image fusion. Ideally, image matching should allow for offsets in the target image, and for scaling and rotation. Offsets all...
Measuring the halo mass of z similar to 3 damped Ly alpha absorbers from the absorber-galaxy cross-correlation
high-redshift absorption lines
2014/12/24
We test the reliability of a method to measure the mean halo mass of absorption-line systems such as damped Lyα absorbers (DLAs). The method is based on measuring the ratio of the cross-correlation be...
Two Exponentiation Algorithms Resistant to Cross-correlation Power Analysis and to Other Known Attacks
secret-key cryptography smart cards
2013/2/21
In order to prevent the SPA (Simple Power Analysis) attack against modular exponentiation algorithms, a multiply-always implementation is generally used. Witteman et al. introduced in \cite{WI} a new ...
Locating a scatterer in the active volcanic area of Southern Peru from ambient noise cross-correlation
Interferometry Wave scattering and diffraction Volcanic arc processes
2014/4/10
We report on a strong scatterer of seismic energy in the 5–10 s period range located in the volcanic arc of Southern Peru. It is superficially like an active noise source in that it produces a continu...
Accelerating Radio Astronomy Cross-Correlation with Graphics Processing Units
Radio astronomy Graphics Processing Unit Signal Processing Correlation
2011/10/13
We present a highly parallel implementation of the cross-correlation of time-series data using graphics processing units (GPUs), which is scalable to hundreds of independent inputs and suitable for th...
Cross Correlation of Intra-day Stock Prices in Comparison to Random Matrix Theory
Principal Component Random Matrix Theory Cross Correlation Eigenvalues Stock Market
2013/1/28
We propose and apply a new algorithm of principal component analysis which is suitable for a large sized, highly random time series data, such as a set of stock prices in a stock market. This algorith...
Multifractal detrending moving average cross-correlation analysis
cross-correlations multifractal detrended cross-correlation analysis extensive numerical experiments
2011/3/30
There are a number of situations in which several signals are simultaneously recorded in complex systems, which exhibit long-term power-law cross-correlations. The multifractal detrended cross-correla...
The Spatial Clustering of ROSAT All-Sky Survey AGNs II. Halo Occupation Distribution Modeling of the Cross Correlation Function
The Spatial Clustering ROSAT All-Sky Survey AGNs II
2011/1/11
This is the second paper of a series that reports on our investigation of the clustering properties of AGNs in the ROSAT All-Sky Survey (RASS) through cross-correlation functions (CCFs) with Sloan Dig...
ISW-LSS cross-correlation in coupled Dark Energy models with massive neutrinos
cosmic microwave background cosmology: miscellaneous cosmology observations cosmology: theory cosmology: large-scale structure of universe
2010/11/9
We provide an exhaustive analysis of the Integrated Sach–Wolfe effect (ISW) in the context of coupled Dark Energy cosmologies where a component of massive neutrinos is also present. We focus on the ef...
