Single‐image signal‐to‐noise ratio estimation [PDF]
Scanning, 2001 AbstractA method for estimating the signal‐to‐noise ratio from a single image is presented in this paper. The autocorrelation‐based technique requires that image details be correlated over distances of a few pixels, while the noise is assumed to be uncorrelated from pixel to pixel.

HDR Imaging with Spatially Varying Signal-to-Noise Ratios
2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2023 While today's high dynamic range (HDR) image fusion algorithms are capable of blending multiple exposures, the acquisition is often controlled so that the dynamic range within one exposure is narrow. For HDR imaging in photon-limited situations, the dynamic range can be enormous and the noise within one exposure is spatially varying.

An adaptive bitonic filtering based edge fusion algorithm for Gaussian denoising
International Journal of Cognitive Computing in Engineering, 2022 It is broadly recognized that conserving the essential geometrical features of an image is crucial while denoising it. To accomplish this aim, various denoising techniques have been represented in the literature.
