Profile Viewer

The Profile Viewer provides detailed information about the currently used noise profile. The Profile Viewer provides the following details:

• Overall profile quality – this is an estimation of the overall quality of the noise analysis represented by this profile. The higher this value the better this profile seems to be. A high quality profile is necessary for quality noise reduction.
  
  
• Noise sample – this is an optional noise sample (a crop from the image used to build this profile). The noise sample helps you visually evaluate the noise described by this profile. Also, you can easily see whether any details are present in this area, which makes the profile less accurate (only flat featureless areas without any details should be used for profiling).
  
  
• Clipping – this indicator tells whether there is any clipping in the analyzed image area. Clipping occurs when the sample contains pixels that are very close to or in fact are entirely white (or entirely black). Clipping reduces the overall profile quality.
  
  
• Uniformity – these values show how uniform the noise sample is in all color channels. The uniformity is low when any details are present in the area. Low uniformity reduces the overall profile quality.
  
  
• Fine-tuning – this indicator tells how well this profile is fine-tuned. Fine-tuning is a part of profiling process (both automatic and manual) and the more complete and accurate the fine-tuning the higher the overall profiling quality. If you work with Neat Image in Advanced mode then you can see that the more green shadings are present in the noise profile equalizer the higher the overall profile quality. You can improve the profile quality by additional fine-tuning.
  
  
• Noise levels – these figures show the actual noise levels measured by the analyzers during profiling. There are the overall noise level and noise levels corresponding to channel and frequency image components. These figures are a good indication of how noisy an image source is.
  
  
• EXIF information – this box contains the EXIF information associated with the image used to build this profile. This information is used by Neat Image to find a profile that matches an input image.
