The ''Mean Filter'' tool is used to do a low-pass filter that can emphasize the longer-range variability in an image that essentially smooths the image. It is useful for reducing noise in an image. The algorithm calculates the average value in a moving window centered on each grid cell. The filter size is specified in the x and y dimensions in odd, positive integer values. It works in both greyscale and red-green-blue (RGB) images, however, the RGB images are decomposed into intensity-hue-saturation and the filter applies to the intensity channel.

Mean Filter
The Mean Filter tool is used to do a low-pass filter that can emphasize the longer-range variability in an image that essentially smooths the image. It is useful for reducing noise in an image. The algorithm calculates the average value in a moving window centered on each grid cell. The filter size is specified in the x and y dimensions in odd, positive integer values. It works in both greyscale and red-green-blue (RGB) images, however, the RGB images are decomposed into intensity-hue-saturation and the filter applies to the intensity channel. NoData values are ignored.
Input Parameters
- Input raster file: –
- Size of the filter kernel in the x-direction: – Enter the number, an odd, positive integer for the x dimension. Default is 3.
- Size of the filter kernel in the y-direction: – Enter the number, an odd, positive integer for the y dimension. Default is 3
Output Parameters
- Output raster file: – Enter the name of the newly created raster file.
