Learning Phase Distortion with Selective State Space Models for Video Turbulence Mitigation

CVPR 2025highlight

Atmospheric turbulence is a major source of image degradation in long-range imaging systems. Although numerous deep learning-based turbulence mitigation (TM) methods have been proposed, many are slow, memory-hungry, and do not generalize well. In the spatial domain, methods based on convolutional op…

Spatio-Temporal Turbulence Mitigation: A Translational Perspective

CVPR 2024poster

Recovering images distorted by atmospheric turbulence is a challenging inverse problem due to the stochastic nature of turbulence. Although numerous turbulence mitigation (TM) algorithms have been proposed their efficiency and generalization to real-world dynamic scenarios remain severely limited. B…

Accelerating Atmospheric Turbulence Simulation via Learned Phase-to-Space Transform

ICCV 2021poster

Fast and accurate simulation of imaging through atmospheric turbulence is essential for developing turbulence mitigation algorithms. Recognizing the limitations of previous approaches, we introduce a new concept known as the phase-to-space (P2S) transform to significantly speed up the simulation. P2…
