"instead of filtering static image, treat single infrared frame as part of temperature sequence during thermal equilibrium... 3-step non-linear spatio-temporal transformation creates/ analyzes filters simulating IR image sequences at different temperature intervals finding spatio-temporal correlations... Zero-Reference Deep Curve Estimation model constructs high-order, pixel-level curve to map out and predict the final enhanced image... firefighting masks"
