Using the Noise Tab

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 Noise tab settings are intended for black and white scanning; they have no effect on

grayscale scanning.

To change the Noise settings

From the VRS Interactive Properties dialog, select the Noise tab.

Under Enhancement Filters, you can select one of the following:

a None: Disables all the enhancement filters.

b Descreening: Activates a shade removal filter that is useful for removing halftone

patterns.

c Image smoothing: Activates a filter that helps to smooth characters or lines that

appear jagged on your image.

d Image cleanup: Activates a filter that smooths out characters, removes background

noise, and eliminates some lines.

Use the Erosion/Dilation Slider to select the amount of thinning/thickening to apply to

image elements.

a For image elements that are ballooned or blended together, improvement occurs as

you move the slider toward the Thin setting.

b For image elements that are too thin or too light, improvement occurs as you move

the slider toward the Thick setting.
