Segmentation: The Achilles’ heel of object–based image analysis?
digital cartography spatial framework segmentation land cover
2015/11/16
Much of the background material on geo-object-based image analysis (GEOBIA) begins with a description of image segmentation
and suggest it as the first stage of the process. Although this approach m...

2015/11/16
In the last two decades, advances in computer technology, earth observation sensors and GIS science, led to the development of
“Object-based Image Analysis (OBIA)” as an alternative to the tradition...
COMPARISON OF PIXEL- AND OBJECT-BASED SAMPLING STRATEGIES FOR THEMATIC ACCURACY ASSESSMENT
Quality object-based pixel-based confusion matrix samples
2015/11/16
Confusion matrix and derived global indices (kappa, overall accuracy, producer accuracy) are widely accepted as a standard method
for the accuracy assessment of land use/land cover maps. In order to ...
