Deconvolution

[Channel Hopper]

or how to focus an object that is fuzzy.

In general, the object of deconvolution is to find the solution of a convolution equation of the form:

Usually, h is some recorded signal, and ƒ is some signal that we wish to recover, but has been convolved with some other signal g before we recorded it. The function g might represent the transfer function of an instrument or a driving force that was applied to a physical system. If we know g, or at least know the form of g, then we can perform deterministic deconvolution. However, if we do not know g in advance, then we need to estimate it. This is most often done using methods of statistical estimation.

It reminds me of the system that was introduced during the Apollo landings on the moon. I don't know what it was called but effectively it removed a fair whack of noise from the signal and greatly improved the picture quality.

A studio ?

No, real life.

You can tell the difference can't you?

Not always, besides reality - at least for mere mortals - normally requires consensus otherwise it can be dismissed as little more than a temporary break from the universal chaos.

(and yes, they did go to the moon)

I sense a Stork moment coming on.
