Image denoising is a computer vision technique that removes noise from images while preserving essential structures and textures. It plays a critical role in applications such as photography enhancement, medical imaging, and remote sensing.
To address such problems, we have employed GUSL, a Green Learning-based pipeline tailored for image denoising. Noisy images are resized to multiple resolutions, and Green Learning techniques such as PixelHop, RFT, and LNT are applied at each level to extract features independently. Each level progressively refines the denoising result by correcting the residuals from the previous level. While this approach yields promising results, further refinement is needed to enhance performance in smooth and texture-rich regions.
