to the plugins folder, or subfolder, restart ImageJ,
and there will be a new “Calculate 3D Noise” command in the Plugins menu,
This ImageJ plugin calculates the 3D-noise from a sequence
of images. 3D noise is a technique for describing the noise in
a video that tries to break down the analysis into various
components which helps to determine where the noise comes
from. For example, flicker noise (the t-component) is when
the average brightness of the image jumps around. Or rain
noise (the th-component) is like what was used in the Matrix
movies. Various ratios (say, vh/tvh) are general indicators
of the niceness of a video system.
The 3D-noise algorithm follows that developed by
the Night Vision Lab (or Night Vision Electronic
Sensor Directorate) at Fort Belvoir, VA.

1) Open an image sequence or video file and selects an ROI.
2) Run this plug-in
3) Verify the ROI.
4) Input a Signal Transfer function (SiTF).
This plugin was developed to analyze the 3D-noise
of infrared images. Thus, the SiTF has units to
convert image signal to degrees-Centigrade.
Output in Results window includes:
a) Eight 3D-noise components and the temporal noise.
If an SiTF is entered, the units are milli-Kelvin.
b) The SiTF (if used)
c) The mean image signal within the ROI
d) Size of the "Data Cube": height, width, # frames
