Image Averaging
Frame Averaging provides a way to average multiple video frames
to create a more stable image. This module can be used
to eliminate pixel vibrations or high frequency image
changes.
The frame averaging works by adding each frame into a moving
average of frames. This effectively creates the same effect
of averaging many frames without the significant memory and time
that averaging hundreds of frames would take.
The averaging effect
can be used to remove fast moving objects from frames if a high frame
averaging is used. If fewer frames are averaged the effect creates
a washing or strobe like effect (way cool!!).
Interface
Example
Averaging of 4 frames. Click to view (345 Kb AVI)

2. Continuous - Specify if the averaging should be continuous or stop after the specified number of frames have been averaged.
