THE LOW BACKSCATTERING OBJECTS CLASSIFICATION IN POLSAR IMAGE BASED ON BAG OF WORDS MODEL USING SUPPORT VECTOR MACHINE
Low Backscattering Objects Bag of Words SIFT features Support Vector Machine
2018/5/16
Due to the forward scattering and block of radar signal, the water, bare soil, shadow, named low backscattering objects (LBOs), often present low backscattering intensity in polarimetric synthetic ape...
Data Filtering and Feature Extraction of Urban Typical Objects from Airborne LIDAR Point Cloud
LIDAR Filtering Aerial Survey Feature Extraction Buildings Airborne Scanner Systems Urban Planning
2015/12/8
The research in the detection and feature extraction of typical objects in urban areas has intensified. In existing detection technologies, it has been shown that the LIDAR technique is very promising...
Pre-classification of Points and Segmentation of Urban Objects by Scan Line Analysis of Airborne LIDAR data
Laser scanning LiDAR airborne remote sensing on-line processing
2015/12/4
Currently available laser scanners are capable of performing hundreds of thousands of range measurements per second at a range resolution of a few centimeters. Despite that increasing performance, up ...
Curvelets–A Surprisingly Effective Nonadaptive Representation For Objects with Edges
Curvelets Nonadaptive Representation Objects with Edges
2015/6/17
It is widely believed that to efficiently represent an otherwise smooth object with discontinuities along edges, one must use an adaptive representation that in some sense ‘tracks’ the shape of the di...
EXTRACTING 3D FREE-FORM SURFACE BOUNDARIES OF MAN-MADE OBJECTS FROM MULTIPLE CALIBRATED IMAGES: A ROBUST, ACCURATE AND HIGH RESOLVING POWER EDGEL MATCHING AND CHAINING APPROACH
Photogrammetry 3D Reconstruction
2015/5/18
This paper describes a purely geometrical approach for matching and chaining edgels, i.e. contours points with their tangent direction,
to reconstruct in a general way 3D rectilinear or curved surfac...
