GLOBAL REGISTRATION OF KINECT POINT CLOUDS USING AUGMENTED EXTENDED INFORMATION FILTER AND MULTIPLE FEATURES
Global registration Kinect Augmented extended Information filter Point cloud fitting Indoor mapping
2016/10/14
Because the Infra-Red (IR) Kinect sensor only provides accurate depths up to 5 m for a limited field of view (60°), the problem of registration error accumulation becomes inevitable in indoor ma...
The purpose of this note is to demonstrate that a weak form of club guessing on ω1 implies the existence of an Aronszajn line with no Countryman suborders. An immediate consequence is that the existen...
FIR filter design via spectral factorization and convex optimization
Finite impulse response filter filter coefficient variables spectral decomposition linear and nonlinear convex programming
2015/8/11
We consider the design of finite impulse response (FIR) filters subject to upper and lower bounds on the frequency response magnitude. The associated optimization problems, with the filter coefficient...
Filter design with low complexity coefficients
Heuristic design low complexity coefficient filters with nonzero number the filter coefficients
2015/8/10
We introduce a heuristic for designing filters that have low complexity coefficients, as measured by the total number of nonzeros digits in the binary or canonic signed digit (CSD) representations of ...
Comparison of the ensemble Kalman filter and 4D-Var assimilation methods using a stratospheric tracer transport model
the ensemble Kalman filter 4D-Var assimilation methods stratospheric tracer transport model
2014/12/19
An ensemble Kalman filter (EnKF) assimilation method is applied to the tracer transport using the same stratospheric transport model as in the four-dimensional variational (4D-Var) assimilation system...
Error reduction in GPS datum conversion using Kalman filter in diverse scenarios
Datum eastings northings Kalman filter GPS coordinate conversion
2014/11/25
The coordinates of a location obtained from a Global Positioning System (GPS) receiver
depend on the type of environments. This paper discusses the errors in GPS coordinate
conversion from the Wor...
Marginal Likelihood Computation for Hidden Markov Models via Generalized Two-Filter Smoothing
MarginalLikelihood Sequential MonteCarlo Generalized Two-Filter Smoothing
2012/11/21
In this note we introduce an estimate for the marginal likelihood associated to hidden Markov models (HMMs) using sequential Monte Carlo (SMC) approximations of the generalized two-filter smoothing de...
Large-angle scattered light measurements for quantum-noise filter cavity design studies
Large-angle scattered light measurements quantum-noise filter cavity design studies Optics
2012/4/24
Optical loss from scattered light could limit the performance of quantum-noise filter cavities being considered for an upgrade to the Advanced LIGO gravitational-wave detectors. This paper describes i...
A matched filter maximizes the signal-to-noise ratio of a signal. In the recent work of Corron et al. [Chaos 20, 023123 (2010)], a matched filter is derived for the chaotic waveforms produced by a pie...

Ecological Filter Bed Floating Basket Flyash Cenospheres Water Body Restoration
2011/11/17
A new kind of suspending combination ecological filter bed was constructed, which took floating baskets as basic units and took flyash cenospheres and attapulgite clay ultra light filter material as l...
Filters and open filters are useful utilities to explore structures of domains. In this paper, it is proved that for a continuous distributive semilattice L, OFilt(L) is a distributive lattice iff L i...
