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...
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
