TTTIR: Instance-Specific State Evolution for Image Restoration via Test-Time Training

TTTIR introduces a test-time training framework that models image restoration as progressive instance-specific state evolution, using a Progressive State Sequence Generator for target trajectories and a State Transition Evolver for adaptive operator updates, achieving state-of-the-art results on low-light enhancement, deraining, and dehazing benchmarks with minimal parameters.
