NDNoise consente di eliminare il rumore dalle immagini digitali. Gratuito e scritto in Java, ecco le sue caratteristiche:

• load / save multiple image with the same filter tuning
• multiple image format support: PNG, JPEG, GIF, ... (prefer lossless PNG compression !)
• 3 sliders tuning for basic use: noise removal, dots/spots/lines smoothing, retexturing
• direct visualisation of filtering effect by alternate visualisation
• zoom in/out at any level

Le novità di NDNoise 0.2:

• [Fast] button for easier tuning
• filtering improvement, should avoid some small posterization in special cases
• differential view for filtering control
• fix small interface refreshing bugs

NDNoise è standalone: non necessita di installazione.
