Matching and Registration of line network
from a pair Map/Image


a SPOT image and a cartographic data base


Once the roads are extracted from the image, the aim is the following:

to match the roads from the image and those from the map
to analyze the matching
to improve the registration

  For which applications is it useful ?

map updating
generalization error estimation
guided detection on the satellite image (zooming)
