Using the Noise Panel
Noise in an image consists of pixels accidentally and randomly added to the image
during image processing. The level of shading for these pixels is also random and can
vary quite a bit. Unfortunately, images attained through even the most sophisticated
sensors can still be contaminated by noise sources and they have to be corrected.
You can use the filters on the Noise panel to enhance image quality and remove
excessive speckling. As you adjust the Noise settings, the effects are applied to the
image in the VRS Interactive Viewer window. You can fine-tune the settings until the
image appearance meets your quality standards.
The VRS Noise panel is available only if the scanner is set for bitonal scanning.
