SEMANTIC INDEXING OF TERRASAR-X AND IN SITU DATA FOR URBAN ANALYTICS
Earth-Observation images data mining semantic definition land use land cover analytics
2016/1/15
This paper presents the semantic indexing of TerraSAR-X images and in situ data. Image processing together with machine learning methods, relevance feedback techniques, and human expertise are used to...
Image Localization in Satellite Imagery with Feature-Based Indexing
orthogonal satellite imagery image localization content-based image retrieval
2015/12/4
This paper presents a method to index ortho-map databases with image-based features and search a map database for regions that match query images of unknown scales and rotations. The proposed method u...
Indexing of the Discrete Global Grid Using Linear Quadtree
Indexing The discrete global grid Linear quadtree
2015/8/17
In recent years a method of recursive subdivisions of the triangular faces of the octahedron or icosahedron has been developed for
approximating to the surface of the earth. But the triangle-based di...
SPATIOTEMPORAL INDEXING MECHANISM BASED ON SNAPSHOT-INCREMENT
Version Increment Index Mechanism Spatio-Temporal Model
2015/8/10
Spatio-temporal index is one of the key technologies applied to spatio-temporal database engines. Methods for spatio-temporal indexes which consider efficiency of both temporal queries and spatial que...
AUTOMATIC OBJECT EXTRACTION FROM FULL DIFFERENTIAL MORPHOLOGICAL PROFILE IN URBAN IMAGERY FOR EFFICIENT OBJECT INDEXING AND RETRIEVALS
Urban Object Extraction Segmentation Multispectral Retrieval
2015/8/3
The differential morphological profile (DMP) can be used for automated extraction of multi-scale urban features, such as buildings, shadows, roads, and other man-made objects. However, characterizatio...
