Re: Euclid Discoveries Press Release

Hi all,

I expect that much of this is marketing hype.
The technology they are working on is extremely difficult to make work efficiently, but is not impossible. For compressing a head and shoulders video of say a news cast, this technology would likely get the 4-5x improvement they claim over MP4, but for other sources I expect much less.
For low motion movies and scenes (maybe dramas and the like) it may do well, but for high motion scenes the MP4 technology will actually outperform it (perhaps they would fallback in these cases).

For example, just try a scene with a waterfall, an ocean, an explosion, or heavy rain, and no matter what motion technique you use you will get bad results. Object based motion will not improve these cases.

Still, I remain very interested to see it demonstrated. I also would love to know what resources are required during encoding. I suspect it will be extremely high.

They claiming to have created Object-Based compression technology that
lets them get 460% improvement over H.264 (not sure exactly what that
number means.)

Quotes:

Euclid Discoveries
(http://www.eucliddiscoveries.com), a video compression firm, announced
that
its technology has achieved compression ratios of 15,168 to 1 for
certain
videos. The technology, called EuclidVision(TM), greatly exceeds the
current
standard for digital video with a 460 percent improvement over MPEG-4,
which
implies more than a 600 percent improvement over DVD video format
MPEG-2 for
certain videos.

...

EuclidVision uses a new generation of video compression known as
"Object-Based Compression" or "OBC," which refers to technology that
analyzes
shapes in the video to achieve higher compression ratios.

...
The architects of MPEG-4 technology envisioned OBC as the future for
this
video standard but, before Euclid Discoveries, no firm managed to make
it
work. The MPEG-4 standard anticipates object-based compression through
"Object Planes," facial modeling, and 3D object modeling -- providing
only a
definition of these concepts without providing the means of employing
them
toward the goal of high compression ratios.

...
For streaming commentator video, Euclid can reduce a 23 MB video file
to a
1,519 byte file -- effectively enabling sub-4Kbps, low-bandwidth
streams for
wired and wireless applications. The streaming commentator application
provides a rigorous proving ground for EuclidVision

..

Ultimately, EuclidVision should
be able to reduce the current MPEG-4 attainable 700 MB file size for
2-hour
long videos down to 50MB -- finally making feature length movies as
"swappable" as MP3s.
