Rapid method for target motion detection using the spatiotemporal constraint equation

We have developed a computationally rapid method of target motion detection using the spatio-temporal constraint equation [1]. This method requires significantly fewer computations than standard methods based on the same equation, and appears to work well even under poor image conditions, such as low contrast, small object size, camera jitter, poor focus, and minimal in-plane motion. This paper will describe both the standard method and our more rapid approach, and will discuss enhancements added to mitigate the effects of registration error and camera jitter. Results, indicating object motion in infrared video images, will be presented.
