Any removed energy, is collected per pixel and re-distributed across the image in a second pass, giving the user intuitive control, via the 'Grain Dispersion' parameter, over a hard upper size limit beyond which grain is no longer smoothed out.
I'm relatively new to image processing and just wanted to say how straight forward and powerful StarTools is.
The Stereo 3D module can be used to synthesise depth information based on astronomical image feature characteristics.
Select the 'decode the data from a Base64 string (base64 decoding)' radio button.
Noise reduction and grain shaping is performed in three stages.
The module can also be used as swiss pocket knife for gamma correction, normalisation and channel luminance contribution remixing.
You can convert everything you see to a format you find convenient. Give it a try!
