Data segmentation for geometric feature extraction from lidar point clouds
TLDR
We present a method to partition 3D point clouds into useful segments from Light Detection and Ranging (LIDAR) data directly without previous digital surface model generation. Expand

Assessing leaf photoprotective mechanisms using terrestrial LiDAR: towards mapping canopy photosynthetic performance in three dimensions.
Terrestrial laser scanning (TLS) data allow spatially explicit (x, y, z) laser return intensities to be recorded throughout a plant canopy, which could considerably improve our understanding of howExpand

Filtering of airborne Lidar point clouds for complex cityscapes
TLDR
A novel filtering algorithm for Lidar point clouds is presented, which can work well for complex cityscapes and has no impact of size and shape of buildings. Expand

STATISTICAL CHANGE DETECTION BASED ON CAUCHY DISTRIBUTION FOR VISUAL SURVEILLANCE
A novel illumination-invariant change detection algorithm based on Cauchy distribution is proposed. The intensity ratios between two images are used as the feature to model and subtract background.Expand

AN INTEGRATED SYSTEM OF DIGITAL VIDEO CAPTURING SYSTEM, GPS AND GIS FOR RADAR CLUTTER ANALYSIS
Radar clutter is very complicated signal, because it is a kind of random process and invisible to human. As a result, besides instrumental parameters, environmental parameters will play a criticalExpand
