Title:
Automatic estimation of vehicle activity from airborne thermal infrared video of urban areas by trajectory classification 
Abstract:
Analysis of traffic data plays an important role in urban and spatialplanning. Thermal Infrared (TIR) video cameras have capabilitiesto operate at day and night and to acquire the scene sampled withvideo frame rate. In this paper a strategy for the estimation ofvehicle motion and the assessment of traffic activity from airborneTIR video is presented. In contrast to other approaches we handledetecting and tracking vehicles in the video separately, becausemoving as well as stationary vehicles are...    »
