Enhancing Images of Permanently Shadowed Lunar Crater Regions Using BM3D Denoising Algorithm.

Permanently shadowed regions (PSRs) on the moon are expected to contain large amounts of water and ice, which is crucial for sustainable exploration of the moon and beyond. However, there is limited information about small-scale features and ice distribution within the PSRs due to low resolution and/or poor quality of the orbital imagery captured. This paper proposes a method to use the existing general-purpose algorithm, Block-Matching and 3D Filtering (BM3D), to denoise the noisy crater images. [ABSTRACT FROM AUTHOR]
