Honors Theses at the University of Iowa

While the development of automatic object recognition and vectorization algorithms to be used on scanned or digitized maps is a vibrant area of study today, most are not developed for or suitable for use with either historical maps in general or archaeological field maps both historic and modern. Current algorithms use methods such as line thinning and other approximation techniques while also relying on continuous lines and features as well as color/greyscale spectrums in the source maps to function. These often are not present in hand-drawn field maps or very old maps which can contain many irregular features and ...
