A warm ceramic bunny sits in still air while a gentle wind draft passes through the scene.
Convective heat plumes rising from the surface become visible after processing, revealing
how the airflow disturbs and carries heat away from the object.
A figurine of Yoda is observed in thermal video. Subtle emissivity differences across
the surface — particularly around the eyes — produce faint periodic signals
that our method isolates and amplifies.
A keyboard and book are filmed after brief contact with a warm hand. Residual heat
conduction patterns spread slowly across the surfaces, leaving thermal fingerprints
that are invisible in raw footage but clearly revealed after processing.
Hot exhaust gases emanating from a vehicle are captured against an ambient background.
The turbulent thermal plume is largely imperceptible in raw microbolometric footage
but becomes strikingly visible after temporal processing.
A spinning fan redistributes warm air in its vicinity, creating structured turbulent
currents. Processing the microbolometric video reveals the periodic air movement and
heat redistribution patterns driven by the fan's rotation frequency.
A linear polarizer is rotated in front of the thermal camera. The apparent thermal
emission of surfaces changes with polarizer angle due to polarization-dependent
emissivity, producing subtle periodic intensity oscillations our method captures.
Longwave infrared bandpass filters are placed in the optical path, selectively
transmitting narrow spectral bands. Differences in spectral emission across
materials become measurable, revealing material-dependent thermal signatures
invisible in broadband thermal imaging.
