Abstract

This paper details recent work in our group on the use of low-level features for the identification of man-made regions in unmanned aerial vehicle (UAV) imagery. The feature sets that we have examined include classical statistical features such as the coefficient of variation in a window about a pixel, locally computed fractal dimension, and fractal dimension computed in the presence of wavelet boundaries. We will discuss these techniques of feature extraction along with our approach to the classification of the features. Our classification work has focused on the use of a new semiparametric probability density estimation technique. In addition, we will present classification results for region of interest identification based on a set of test images from a recent UAV test flight.
