| Abstract: | Various technologies pertaining to modeling patterns of activity observed
in remote sensing images using geospatial-temporal graphs are described
herein. Graphs are constructed by representing objects in remote sensing
images as nodes, and connecting nodes with undirected edges representing
either distance or adjacency relationships between objects and directed
edges representing changes in time. Activity patterns may be discerned
from the graphs by coding nodes representing persistent objects like
buildings differently from nodes representing ephemeral objects like
vehicles, and examining the geospatial-temporal relationships of
ephemeral nodes within the graph. |
