Our method involved the description of a differential geometry approach for road seed pixel detection in terms of wavelet transforms. Using this approach allowed us to extend the differential geometry approach to incorporate multiple scales. We found that using multiple scales significantly reduced the number of potential false positives. Our approach seemed to work well with a computer-assisted approach where the "seed" or potential pixels of interest should have a high confidence level of being correct. We found that our approach led to an effective method for detecting roads in aerial imagery. Our method is general, and in principle could be applied to other filtering techniques besides the one used here.
