Temporal Recursive Web Page
The Temporal Recursive web page is active only on the KAM-XM-UNC
module.
This is a motion adaptive temporal recursive filter that works well in
removing random and Gaussian noise. Refer to
Temporal Recursive Filtering
on page 27 for a discussion on using this filter.
Enable the Temporal Recursive control by selecting On in the Enable pull-
down.This filter can operate in either Auto or Manual mode.
Auto Mode
Use the following controls for removing noise:
• Red Overlay – when enabled ( On ), a red overlay is superimposed onto
areas in the input image where the temporal recursive filter identifies
motion.
• Auto – enabling this mode ( Figure 28 ) engages a feedback controller that
dynamically sets the Distance , No Motion and Motion control setting avail-
able in Manual mode based on noise and motion measurement extracted
from the scene.
• Bias – is active only in Auto mode. This control adjusts the noise set point
in the temporal recursive controller. The higher the bias the more
aggressive the controller is towards noise in the scene. The lower the
bias setting the more sensitive the controller is towards motion.
