Title:
Airborne monitoring of vehicle activity in urban areas 
Abstract:
We describe possibilities to extract vehicles from data of differentairborne sensor systems. We focus on three frequency domains, namely(i) visual, (ii) thermal IR and (iii) radar. Corresponding to thedata different processing methods are demanded.(i)Vehicle detectionin aerial images relies upon local and global features. For modellinga vehicle on local level, a 3D-wireframe representation is used describingprominent geometric and radiometric features of cars including theirshadow region. A vehi...    »
