Spike Web Page
The Spike web page ( Figure 26 ) is active only on the KAM-XM-UNC
module.
This web page provides noise reduction with an adaptive median filter that
works well in reducing random impulse noise. Refer to
Spike Filtering on
page 26 for a discussion of the Spike filter.
• Enable – enable or disable the Spike control with the Enable pulldown.
• Luma & Chroma – sets the adaptive threshold of the filter in the luminance
and chrominance channels. This threshold represents a percentage of
the central pixel value that surrounding neighbors must be within in
order to be considered similar.
Setting the filter to 100 (maximum) forces the filter on for every pixel,
resulting in a standard median filter being applied to the entire lumi-
nance and chrominance channels.
