Latest Patents

One of Nash's latest patents is a system for real-time moving target detection using vision-based image segmentation. This innovative system processes video signal information to identify pixels associated with moving objects, even in the presence of platform or sensor-induced motion. The technology employs frame differencing with self-adjusting noise thresholds to detect motion pixels against the background. A field-by-field motion pixel map is generated, allowing for effective tracking of moving objects. The system utilizes a two-step pixel grouping process, where the first pass operates in real-time as the video signal is received, linking pixel groups into a table. The second pass works on a smaller set of link data, reordering entries in the table for efficiency.
