| Abstract: | Image denoising is a fundamental challenge in digital image processing, crucial for enhancing visual qual- ity and ensuring reliable analysis in fields such as medical imaging, surveillance, and satellite image interpretation. This paper proposes a hybrid denoising framework combining the Discrete Wavelet Transform (DWT) with the Non-Local Means (NLM) filter to efficiently remove Gaussian noise while preserving edges and fine image structures. The DWT decomposes the image into multiscale frequency components, allowing targeted denoising of high-frequency bands, while the NLM exploits patch redundancy to smooth noise with minimal blurring. Additionally, Canny edge detection is incorporated to reinforce edge structures during reconstruction. Experimental results on standard test images demonstrate that the proposed method achieves superior performance in terms of Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM), outperforming conventional filtering techniques. |
