6. Using Component viewer and Variant selector
6.1. Component Viewer
The Component Viewer is intended for detailed examination of both frequency and channel
components of images. Examining the components and the filtration masks may be useful to find the
optimum filter settings easier and faster.
⇒ Working with the filter, turn on the Component
Viewer window by clicking on
(the
Component Viewer on/off button) on the toolbar or
by selecting the View | Component Viewer menu
item. The window will pop up to show the image
components of the selected image area (see the
selection in the Filtration Job Editor window).
Examine individual image components as well as filter masks for each channel and frequency
component (use selectors on top of the Component Viewer). To switch on the filter masks, click
(the Show filtration masks button). To switch between original and filtered image (or image
component) simply click on one of the images in the Component Viewer.
Red masks indicate the areas where the standard (aggressive) noise
filtration is applied (see the upper left part of the picture on the right).
Adjust noise filter settings (noise levels) to have red masks covering all
featureless areas. Do not let any noise remain uncovered by these masks.
Green masks indicate the areas where important image details have been
detected and a special type of noise filtration is applied. This type of
filtration is more delicate than the standard one; it is used to preserve the
visible details.
Blue masks indicate the areas where sharpening is applied.
6.2. Variant Selector
The Variant Selector is intended for side-by-side comparison of
several variants of filtration applied to a selected image area. When
you consecutively adjust filter settings you get several possible
variants of filtration. To select the best of these variants use the
Variant Selector.
⇒ Turn on the Variant Selector by clicking on
(the Variant
Selector on/off button) on the toolbar or by selecting the View |
Variant Selector menu item. The window will pop up to
enable adding, sorting, deleting and selecting the variants.
⇒ To add a filtration variant to the Variant Selector, select an area in the input image and let Neat
Image prepare a preview of filtration for this area. This is usually done by Neat Image
automatically. As soon as the preview is ready, this new variant of filtration is added to the Variant
Selector. This happens automatically if Auto add variants is checked in the Variant Selector
window. To manually add a new variant, click
(the Add new variant button).
If you change any filter setting then another filtration variant is prepared and added to the Variant
Selector by Neat Image.
⇒ When several variants are listed in the Variant Selector, you can click any of them to see the
filtration result in the image viewer area of the Variant Selector. Click on this result to temporarily
switch to the unfiltered image. Move to other variants (using the mouse or arrow keys) to compare
filtration variants.
