Usage Instructions
Denoise Modes
Mean filter: replaces center pixel with neighborhood average, good for light noise. Median filter: replaces with median value, best for salt-and-pepper noise. Gaussian filter: weighted average by Gaussian distribution, smooths noise while preserving edges.
Strength Parameter
Higher strength means wider filter range and stronger denoising, but more detail loss. Start from low strength and adjust gradually to balance denoising and detail preservation.
Tips
