Vehicle Detection in Low-Altitude Aircraft Video

Detecting moving ground vehicles from airborne video is a difficult problem because all pixels in the image are moving due to the self motion of the camera.We present a technique based on the normal component of the residual flow algorithm applied on using SURF operator stabilized frames to detect moving vehicles.Experiments show using SURF operator can improve the image stabilizing algorithm speed without loss of accuracy and this approach can effectively detect the moving vehicles.This method and airborne platform can be used as a new attempt to traffic information collection when the routine method can not be used.
