                         allow pan-tilt-zoom functionality and are also subject to wind 
                         load and mount vibrations, thus causing video frame misalignment. 
                         Although algorithms for motion detection, a basic block of most 
                         visual surveillance systems, are relatively mature for fixed 
                         cameras, they usually perform poorly for active and/or vibrating 
                         cameras. The issue is particularly severe for algorithms using 
                         multiple video frames jointly. In this paper, we extend our 
                         earlier work on multiple-frame motion detection to the case of 
                         active and unstable cameras. Our method accounts for 
                         spatially-affine, inter-frame transformations that can vary in 
                         time, uses a variational formulation and applies a level-set 
                         solution. We present ground-truth and real-data experimental 
                         results and show significant improvements over earlier methods.
