Neat Image user guide / Filtration process overview

Overview of filtration process

The Filtration Job Editor is used to filter one image. The Filtration Job Editor window usually opens when you create a new filtration job. When you start Neat Image for the very first time, the Filtration Job Editor window opens automatically.

Using the Filtration Job Editor you can:


1. Open an input image - the image viewer will display the input image; - the information panel will display relevant image data;

2. Prepare a device noise profile - noise analysis necessary to filter the image

- you can open a ready-made profile
or
build a new one on the spot;

- to build a new profile click the Auto Profile button;

this will automatically select and analyze a featureless (noise-only) image area;

if you see that automatic selection includes any important image details then move the selection or manually select another area and click the Auto Profile button again;

3. Adjust the noise filter and sharpening settings to achieve desired level of noise reduction and sharpening

- click the Preview button and Neat Image will automatically select an image area and prepare a preview;

- adjust the filter settings:
try to vary the Noise Reduction Amount: Luminance channel and observe how the preview changes;

- as soon as you are happy with the preview proceed to the next stage;


4. Process the input image - apply filter to the whole image; - when processing is finished, evaluate the resulting output image by comparing it with the input image; - save the output image to a file on the disk.
