This remarkable feature is responsible for never-seen-before functionality that allows you to, for example, apply deconvolution to heavily processed data. The deconvolution module "simply" travels back in time to a point where the data was still linear (normally deconvolution can only correctly be applied to linear data!). Once travelled back in time, deconvolution is applied and then Tracking forward-propagates the changes. The result is exactly what your processed data would have looked like with if you had applied deconvolution earlier and then processed it further.
Sequence doesn't matter any more, allowing you to process and evaluate your image as you see fit. But wait, there's more!
Time traveling like this is very useful and amazing in its own right, but there is another major, major difference in StarTools' deconvolution module.
The major difference, is that, because you initiated deconvolution at a later stage, the deconvolution module can take into account how you processed the image after the moment deconvolution should normally have been invoked (e.g. when the data was still linear). The deconvolution module now has knowledge about a future it normally is not privy to in any other software. Specifically, that knowledge of the future tells it exactly how you stretched and modified every pixel - including its noise component - after the time its job should have been done.
You know what really loves per-pixel noise component statistics like these? Deconvolution regularization algorithms! A regularization algorithm suppresses the creation of artefacts caused by the deconvolution of - you guessed it - noise grain. Now that the deconvolution algorithm knows how noise grain will propagate in the "future", it can take that into account when applying deconvolution at the time when your data is still linear, thereby avoiding a grainy "future", while allowing you to gain more detail. It is like going back in time and telling yourself the lottery numbers to today's draw.
What does this look like in practice? It looks like a deconvolution routine that just "magically" brings into focus what it can. No local supports, luminance masks, or selective blending needed. No exaggerated noise grain, just enhanced detail.
And all this is just what Tracking does for the deconvolution module. There are many more modules that rely on Tracking in a similar manner, achieving objectively better results than any other software, simply by being smarter with your hard-won signal.
StarTools' Deconvolution module allows for recovering detail in seeing-limited and diffraction-limited datasets.
The Bin module puts you in control over the trade-off between resolution, resolved detail and noise.
However the Synth module can physically model and emulate most real optical systems and configurations to obtain a desired result.
This is a basic workflow showing how real-world, imperfect data from a DSLR can be processed in StarTools.
The Entropy module works by evaluating entropy (a measure of "busyness" or "randomness") as a proxy for detail.
You can convert everything you see to a format you find convenient. Give it a try!
