OBJECT-BASED IMAGE ANALYSIS BEYOND REMOTE SENSING–THE HUMAN PERSPECTIVE
OBIA GEOBIA GIScience place bona fide objects
2016/11/24
We introduce a prototypical methodological framework for a place-based GIS-RS system for the spatial delineation of place while incorporating spatial analysis and mapping techniques using methods from...
POLE-LIKE OBJECT EXTRACTION FROM MOBILE LIDAR DATA
LiDAR Point Clouds Local Roughness Graph Cuts based segmentation Pole-like object detection DBSCAN based point clustering
2016/7/5
Object detection and recognition from LiDAR (Light Detection And Ranging) data has been a research topic in the fields of photogrammetry and computer vision. Unlike point clouds collected in well-cont...
EXPERT SYSTEM BASED ON OBJECT-ORIENTED APPROACH FOR LAND COVER MAPPING
Expert classification Object-oriented classifier land cover decision tree segmentation
2015/12/31
The hybrid classifier is presented in combination of expert system and object oriented approach, for which increased information is added for classification and improve the accuracy. Instead of the or...
An Accuracy Assessment Measure for Object Based Image Segmentation
Segmentation ASTRO BerkeleyImageSeg Ecognition Definiens
2015/12/17
Traditional approaches to accuracy assessment are inadequate for object oriented image processing. We tested some measures to assess the accuracy of object based image segmentation in a supervised con...
Geometric and Radiometric Modeling of the Martian Surface Based on Object Space Matching and Photoclinometry
Planetary Cartography Radiometry Matching Visualization
2015/12/17
The unique image data of the High Resolution Stereo Camera (HRSC) on Mars Express enable for systematic derivation of Digital Terrain Models (DTMs) and orthoimages. Consequently, several photogrammetr...

The paper proposes an object-oriented spatio-temporal data model based on space-time composite by taking advantage of high topological representation ability of the space-time composite data model and...
OBJECT-BASED CLASSIFICATION OF INTEGRATED MULTISPECTRAL AND LIDAR DATA FOR CHANGE DETECTION AND QUALITY CONTROL IN URBAN AREAS
Change Detection classification quality control multispectral LIDAR
2015/8/3
Digital spatial data are underlying strong temporal changes. The typical approach of updating these changes is to check the data manually by superimposing them on up-to-date orthoimages from aerial or...
COMBINED ANALYSIS OF HYPERSPECTRAL AND HIGH RESOLUTION IMAGE DATA IN AN OBJECT ORIENTED CLASSIFICATION APPROACH
