A STUDY OF FEATURE POINTS EXTRACTION BASED ON POINT CLOUD DATA SETS AND MODEL SIMPLIFICATION IN GOAF
Feature Points Extraction 3D laser scanner Point Cloud Data Sets Model Simplification Goaf
2016/3/17
The shape measurement of goaf is an important job in mine project. With the rapid development of the measuring equipment, 3D laser scanner, which makes the efficiency of traditional work being improve...
HYPERSPECTRAL IMAGE FEATURE EXTRACTION BASED ON GENERALIZED DISCRIMINANT ANALYSIS
Hyperspectral Image Feature Extraction Generalized Discriminant Analysis Kernel Function
2015/12/30
The hyperspectral image enriches spectrum information, so compared with panchromatic image and multispectral image; it can classify the ground target better. The feature extraction of hyperspectral im...

Atmospheric pollution was previously considered as a 'Brown Cloud’ phenomenon restricted to industrialized urban regions. Studies in field stations and satellite observations made since the last decad...
FEATURE-BASED SPATIO-TEMPORAL DATA MODEL AND ITS APPLICATION IN LANDUSE MONITORING
Spatio-temporal data model feature state of the changing feature-based spatio-temporal data model (SCFSTDM) temporal landuse information system
2015/8/10
Traditional data model takes the geometric object as the modeling target and results directly in decomposing geographic phenomena into a series of objects. Furthermore, the temporal data and spatial d...
Linear Feature Based Aerial Triangulation
feature based photogrammetry orientation parameter estimation
2015/6/1
For the past fifteen years line photogrammetry has been an extremely active area of research in the photogrammetry and computer
vision communities. It differs from traditional analytical photogramme...
RELATIVE POSE ESTIMATION USING IMAGE FEATURE TRIPLETS
Three-view Geometry Line Triplet Matching Relative Orientation Feature Integration
2015/4/1
A fully automated reconstruction of the trajectory of image sequences using point correspondences is turning into a routine practice. However, there are cases in which point features are hardly detect...
CLASSIFIER FOR REMOTELY SENSED IMAGERY USING KOHONEN ’S SELF-ORGANIZING FEATURE MAP WITH REGION GROWING
Remotely Sensed Imagery Self-Organizing Feature Map Region Growing Polar coordinate System
2015/2/4
Applying the region growing to the Kohonen’s self-organizing feature map, a non-supervised classifier for remotely
sensed imagery data is proposed. If the self-organizing feature map is made large e...
