image noise
Case of using automatic profiling
To analyze noise properties, Neat Image uses uniform image areas that contain
noise but no visible or important details. With automatic profiling, Neat Image
tries to find one such area automatically and then uses the found area to analyze
image noise.
- Click
(the Auto
Profile with Regular Image button) on the toolbar, or select the Profile
| Auto Profile with Regular Image menu item, or press F2.
Neat Image will show the image area selected for analysis (see blue selection
box in the image viewer; blue color is an indication of automatic selection)
and will analyze it automatically.
In some difficult cases, Neat Image may have trouble with finding a uniform
featureless area in the image. You will notice that the selected area, for
example, will contain some important image details. In such a case, just move
the selection (or draw a new one) to an area that does not contain any image
details and click the same Auto Profile with Regular Image
button again.
If you see that the area selected for analysis is indeed uniform and featureless,
then you can be sure that noise analysis is accurate. Please simply proceed
to Étape II. Documenting
the noise profile.
