A THRESHOLD-FREE FILTERING ALGORITHM FOR AIRBORNE LIDAR POINT CLOUDS BASED ON EXPECTATION-MAXIMIZATION
Airborne LiDAR Point clouds Filtering Ground points Expectation-maximization Intensity
2018/5/14
Filtering is a key step for most applications of airborne LiDAR point clouds. Although lots of filtering algorithms have been put forward in recent years, most of them suffer from parameters setting o...
SEGMENTATION BASED ROBUST INTERPOLATION – A NEW APPROACH TO LASER DATA FILTERING
Laser scanning Filtering Segmentation
2015/8/13
a general strategies for solving the problem – for filtering can be identified. The first work directly on the measured points and
geometric criteria are used for the decision, if a point is on the g...
TERRAIN MODELING AND AIRBORNE LASER DATA CLASSIFICATION USING MULTIPLE PASS FILTERING
Multiple Pass Filtering ICM Classifi cation DTM
2015/6/1
Airborne laser scanner technique provides a 3D perception of the terrestrial topography, including true ground and objects belonging
either to vegetated areas or to human made features. The high intr...
Particle filtering in high-dimensional chaotic systems
particle filtering in high dimensions chaotic systems Lorenz’96 nonlinear filtering dimensional reduction homogenization
2012/4/20
We present an efficient particle filtering algorithm for multiscale systems, that is adapted for simple atmospheric dynamics models which are inherently chaotic. Particle filters represent the posteri...
This letter demonstrates a novel method to generate high-purity optical millimeter-wave signals with carrier suppression by using a frequency quadrupling technique. To the authors’ knowledge, this is ...
Generation of isolated attosecond pulses in the far field by spatial filtering with an intense few-cycle mid-infrared laser
isolated attosecond pulses the far field intense few-cycle mid-infrared laser
2011/8/5
Abstract: We report theoretical calculations of high-order harmonic generation (HHG) of Xe with the inclusion of multi-electron effects and macroscopic propagation of the fundamental and harmonic fiel...
Quantum Filtering (Quantum Trajectories) for Systems Driven by Fields in Single Photon States and Superposition of Coherent States
Quantum Trajectory Superposition of Coherent States Single Photon States
2011/10/8
Abstract: We derive the stochastic master equations, that is to say, quantum filters, and master equations for an arbitrary quantum system probed by a continuous-mode bosonic input field in two types ...
Quantum Filtering for Systems Driven by Fields in Single Photon States and Superposition of Coherent States using Non-Markovian Embeddings
quantum filtering continuous-mode single photon states continuous-mode superpositions of coherent states quantum stochastic processes
2011/10/8
Abstract: The purpose of this paper is to determine quantum master and filter equations for systems coupled to fields in certain non-classical continuous-mode states. Specifically, we consider two typ...
Behavior patterns of online users and the effect on information filtering
bipartite networks reshuffling process information filtering
2011/8/3
Abstract: Understanding the structure and evolution of web-based user-object bipartite networks is an important task since they play a fundamental role in online information filtering. In this paper, ...
