Median Filter

The FLIR A68/A38 series camera can apply a median 3x3 filter to perform image
smoothing. This filter is applied to the entire image and can be used to reduce image
noise and other artifacts.
The following examples use a zoomed image to show the effects of the median filter at

In addition, Median Filter Mode can be set to Selective, in which case the median filter
is only applied to pixels which are significantly different from their neighbors. This
configuration can be used to replace defective pixels.
