B.V.R. Technologies have some impressive sensor simulation software
which runs on RE2 (multipipe) with all sorts of filters applied using a
combination of graphics hardware and CPU.

It should be possible to use accumulation buffer to simulate temporal
artefacts.

If you really want realistic I.R. databases you should consider building
a dedicated textured database with 1 component textures holding thermal
data, this can produce a very realistic effect while allowing dynamic gain
control & BH/WH by using TV_BLEND & the blendcolour & underlying polygon
colour. Using tluts would provide even more flexibility with this kind of
database.
