Researchers have developed a novel training-free framework for denoising speckle noise in dynamic imaging. This method utilizes a spatiotemporal implicit neural representation combined with an aperture-aware maximum-likelihood formulation to reconstruct clear imagery from noisy observations. The approach explicitly models the spatial covariance of speckle, allowing it to adapt to different pupil geometries without retraining, and employs a matrix-free implementation for practical optimization. Results from simulations and laboratory experiments show enhanced spatial fidelity and temporal consistency compared to existing methods. AI
