Moving object detection for unconstrained low-altitude aerial videos, a pose-independant detector based on Artificial Flow

Automatic detection of moving objects is an important task for aerial surveillance. It has been a popular and well-studied subject for the computer vision community, but is still a challenge. The method we introduce targets surveillance low-altitude mini and micro-UAVs. We take advantage of the inherent image motion on footage captured by such aerial vehicles. Our method confronts Optical Flow vectors and an estimated Flow in order to detect independently moving pixels. This motion-based approach is robust to operational conditions and to the geometric properties of the scene. The efficiency of the method was computed on the VIVID database. The moving areas detected will make the tracking task more robust and efficient.
