Detection and tracking of small moving objects in image sequences by use of nonlinear spatiotemporal optical systems.

We demonstrate the capability of localized structures of spatiotemporal nonlinear optical systems for detection and tracking of small moving objects. Such nonlinear dynamics based image-processing systems are readily implemented using an existing parallel optoelectronic architecture designed for real-time operation.
