Paper Abstract

In this paper we present a procedure for a semi-automatic road extraction from scanned aerial images. We emphasize an intelligent combination of the operator's brain and the hard- and software of the computer in order to facilitate and speed up the whole process. We describe in detail the different modules of the procedure, namely gradient filtering, binarization, skeletonization, edge following and raster-vector conversion. Further we present examples of our results obtained so far.
