Using the Noise Tab
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 a variety of noise sources and they have to be
corrected.
The Noise tab gives you a set of filters that enhance image quality and remove
excessive speckling. As you adjust the Noise settings, the effects are applied to the
image in the VRS Viewer window. You can fine-tune the settings until the image
appearance meets your quality standards.
Note The VRS Noise tab is only available when your scanner is set to do black and
white scanning. In addition, the Enhancement Filter option is not yet available in this
version of VRS; the drop-down box is reserved for future use.
