Researchers have introduced a novel concept called time-reversed imaging, which aims to reconstruct past events in a scene by analyzing residual physical imprints. This approach utilizes multimodal traces, including thermal, ultraviolet, and visible spectra, to infer human-environment interactions that occurred up to three minutes prior. To facilitate this research, a new benchmark dataset named TRACE-HEI has been developed, featuring synchronized tri-modal video sequences of various actions. The proposed method combines multimodal inference with a vision-language-guided diffusion model to generate plausible reconstructions of past frames, demonstrating the feasibility of understanding scenes beyond instantaneous observation.
