The following is from an MIT announcement. I know nothing else about it,  
sorry.

> &nbsp;&nbsp;&nbsp;&nbsp;I shall describe the design and realization of a visual feedback  
> loop for the exploration of reactions to motion on a high performance  
> head/eye platform, with applications in autonomous surveillance,  
> navigation and telepresence. The vision system incorporates a simple  
> model of peripheral and foveal vision, the division being a  
> straightforward one between two scales and two broad functions:  
> detection of new motion and tracking of already detected motion. The  
> aim has been to create simple self-contained motion sensors which run  
> concurrently, quickly and with minimal latency. A video will  
> demonstrate several motion responses: the initiation of motion  
> saccades, a panic response to looming, the opto-kinetic reflex and  
> smooth pursuit. All the motion algorithms run at frame-rate (25Hz) on  
> subsampled/windowed image data, with latencies around 100ms.

> &nbsp;&nbsp;&nbsp;&nbsp;Our work has highlighted the need for efficient algorithms to  
> perform a wide range of visual tasks. I have discovered that a number  
> of estimation problems that involve feature tracking can be posited in  
> a common framework so that the computational complexity of the task is  
> linear with the number of tracked features, making real-time  
> performance feasible. I describe this framework, called the variable  
> state dimension filter (VSDF), and its application to online camera  
> calibration, structure from motion and egomotion determination.
