Here's some fascinating free (for now) software that can apparently turn a sow's ear into a silk purse:

[news.com...]

Among the capabilities of MotionDSP are the ability of "increase resolution, remove compression artifacts, smooth jagged lines, enrich colors, reveal details, and make text readable."

Particularly intriguing is the ability to create a single high-resolution frame from a sequence of frames shot in low-resolution (as with a camera phone). It works better if there is some movement in the scene.

For example, it's possible to read license plates that can't be read in any single frame.

MotionDSP has been funded by In-Q-Tel, the Central Intelligence Agency's venture investment arm.

Don't blame me if the software phones home.

That certainly is fascinating.

As for phoning home, as far as I can see there is no software download.

The service appears to be aimed at cellphone users for now, but the article adds:

MotionDSP also is exploring licensing deals that could enable companies to embed the technology in devices such as set-top boxes. "Everyone wants to take Internet video to the television," but today's low-resolution YouTube videos aren't inspiring on a large screen, he said.

It would be nice to see a report here from someone who has used it.

I think the underlying principles are already in common use in image processing technology. Astronomers, eg, are using sequences of images made with fairly inexpensive CCD image sensors to create sharper images and also to process out atmospheric distortion.

Don't blame me if the software phones home.

Interesting but as with any filter it can destroy details as well, check the full size image out with the balloons that say "Happy Birthday"

You'll notice the painting in the back, the trees appear to have texture in the original but that no longer exists in the after shot. Same with string from balloons and the back of the chair in the corner, both are visble in the original but all but disspear in the after. In that particular example I could probably do better with a couple of simple filters for vdub.

Those samples don't appear to be bringing out really fine "detail" but instead sacrificing it to remove the macroblocking and emphasize instead medium detail.

Do they look better? Certainly but I guess it depends on your perspective but there are already tools available to achieve similar results. Some of the free filters available for virtualdub such as MSU deblocker can certainly achieve similar results.
