AdjustPixelValueOutlier
Sometimes “hot pixels”, pixels whose values deviate too much from the rest of the picture, can be found in images. These kind of outliers may be due to background radiation or also be due to the camera and can affect the image processing negatively if not removed.
Usage
This module can be used to remove hot pixels as determined by the set criteria. The hot pixels are then replaced by pixels within the normal range with specified type.
Example
Here, a very specific example should be given/described. In the future, this can be supported by screenshots etc.. For the moment, give an example easy enough for the user to understand, but specific enough to elaborate why a given parameter is a good set for this very situation.
Modes/Processes
thisIsTheNameOfMode1
Here, a short introduction for the given mode should be placed. Again, state WHAT and WHY this mode us useful in not more than 2 sentences.
Parameters | Description |
---|---|
Adjust outliers | Choose which kind of outliers to deal with |
→ Both | Deal with outliers that are below and above specified multiples of the standard deviation. |
→ Above | Deal with outliers that are above specified multiples of the standard deviation. |
→ Below | Deal with outliers that are below specified multiples of the standard deviation. |
Adjustment type | Choose how to treat outliers |
→ Neighbour average | Replace outliers with the average of the surrounding pixels |
→ Custom value | Replace outliers with the to the mean value of the complete image |
→ Image mean | Replace outliers with a specified custom value |
Deviations from mean [in sdevs] | Choose the multiples of standard deviations from mean that are considered to be an outlier. |
