Space-time compression of FLIR video

Here we discuss space-time processing of tactical forward looking IR (FLIR) video. Using a FLIR data set which does not have the perspicuity of traditional video segments, we apply a succession of simple signal processing operations to improve compression. These include transforms in time and space as well as nonlinear processing. In doing this we separate and process the still and motion parts of the video differently. Using this non-standard method of video processing, we obtain compression up to 5×MPEG with comparable image quality. All processing is amenable to parallel implementation; therefore, real-time processing is possible. The current advantage in compression allows the possibility of real-time transmission over a 64 kbps link.
