NDNoise is a free Java software that eliminates noise from digital images. It is designed to enhance image quality and reduce unwanted graininess.
AbsoluteDeNoiser boasts of several essential features - from loading and saving multiple images with the same filter settings to supporting various image formats like PNG, JPEG, GIF, and more. It is best to use lossless PNG compression for better results. Moreover, it has 3 sliders that are perfect to use for basic wavelength tuning for noise removal, dots/spots/lines smoothing, and retexturing. You can visualize the filter's effect through direct visualization or alternate visualization. Additionally, it has a differential view for filtering control and zooms in/out at any level.
To use NDNoise, Java 1.4.1 or a later version is required. It is worth noting that NDNoise is entirely free for personal use and not commercial purposes. Overall, NDNoise is a must-have if you want high-quality noise reduction filters for your digital images.
