A cognitive approach to road recognition with novel feature indicators (1996)
Journal Article
Varley, D., Visvalingam, M., & Wright, C. (1996). A cognitive approach to road recognition with novel feature indicators. Computer Journal, 39(9), 751-756. doi:10.1093/comjnl/39.9.751

This paper outlines a simple strategy for recognition of prototypical cases of urban roads from their outline forms alone. Two new form indicators, namely exits and occupancy, are used together with average width to label regions as roads. They prove... Read More

Road extraction and topographic data validation using area topology (1994)
Journal Article
Varley, D. A., & Visvalingam, M. (1994). Road extraction and topographic data validation using area topology. Computer Journal, 37(1), 3-15. doi:10.1093/comjnl/37.1.3

A simpler novel process for extracting roads is outlined in this paper. The procedures which were adopted for checking the consistency of semantic labelling is described. And it discusses the extent to which findings should influence the database mod... Read More
