Both InSAR and GPS can detect tropospheric delay of radar beam propagation caused by water vapour fluctuation. What InSAR detected is the differential results of two SAR images taken at two epochswhos...
OPTIMIZED IMAGE SEGMENTATION AND ITS EFFECT ON CLASSIFICATION ACCURACY
Image segmentation Segment based classification Variance Spatial autocorrelation Moran’s Index SPRING McNemar’s test
2015/9/28
Image segmentation is a preliminary and critical step in segment-based image analysis. Its proper evaluation ensures that the best segmentation result is used in image classification. In this paper, i...
YOU DESCRIBE IT,I WILL NAME IT:AN APPROACH TO ALLEVIATE THE EFFECT OF USERS’SEMANTICS IN ASSIGNING TAGS TO FEATURES IN VGI
Uncertainty VGI Users’ Semantics Tagging Features OpenStreetMap Perception
2015/9/21
As an important factor of VGI quality, this paper focuses on uncertainty arisen in assigning tags to features by VGI users. The VGI portals ask their users to assign (or tag) one or more data types to...
