interrelations described in this paper. Context objects can also
be beneficial in the next steps, which include the formation of a
road network by searching for junction hypotheses between
road strings and removing isolated (mainly falsely extracted)
road parts. The completeness and correctness values given in
this paper where obtained from the single road parts. They are
likely to improve during the network generation because the
majority of falsely extracted road parts can be removed and the
gaps between road parts in a string can also be counted as road.
ACKNOWLEDGEMENTS
This project is funded by the DFG (German Research
Foundation) under grant HE 1822/21-1. The calculation of the
normalized cuts was made with a C++ program partly adapted
from a MATLAB program written by Timothée Cour, Stella Yu
and Jianbo Shi. Their program can be found at
www.seas.upenn.edu/~timothee/software_ncut/software.html
(accessed March 2009). The calculation of the linear program
was made with the MILP solver lpsolve
(lpsolve.sourceforge.net/5.5/, accessed March 2009).
