Arithmetic mean filter
From AWF-Wiki
Arithmetic mean filter is commonly used for noise reduction. The filter computes the value of each output pixel by finding the statistical mean of the neighborhood of the corresponding input pixel (Fig. A).
- In the search engine of the Processing Toolbox, type Smoothing and select Smoothing(mean) under Image Filtering of the Orfeo Toolbox.
- Under the Parameters tab, select a single band or a multiband file as input layer.
