Motion Model vs motion vector in Nokia's motion-predictive-encoding patents
Authored by: Anonymous on Wednesday, March 27 2013 @ 02:49 AM EDT
There is a family of Nokia US patents based on application
09/371,641; http://portal.uspto.gov/pair/PublicPair shows:

09/489,327 filed on 01-21-2000 which is Patented
09/637,773 filed on 08-11-2000 which is Patented
10/778,449 filed on 02-13-2004 which is Patented
11/609,873 filed on 12-12-2006 which is Pending
PCT/US00/21823 filed on 08-10-2000 which is Published
PCT/US00/21824 filed on 08-10-2000 which is Published
10/795,083 filed on 03-05-2004 which is Patented

These patent documents all describe motion-predictive video
encoding, and use the terms "motion model" and "motion
vector field" to talk about methods which reconstruct a
macroblock not just by translating it as a whole (an older
technique using a single "motion vector" for the entire
block of pixels), but by moving each individual reference
pixel by its own individual motion vector. This method
allows a few coefficients to precisely describe scale,
rotation, and shearing types of optical flow.

VP8 does not use fancy motion models, it uses old-fashioned
single-motion-vector-per-block motion prediction.

The question is, does Nokia propose that their "motion
model" patents cover the simple motion vector methods as a
special, trivial, case of a multi-coefficient affine
transform? If they don't -- and I think a good argument
could be made that the descriptive text of the patent makes
clear that Nokia's "motion model" term refers specifically
to an improvement over simple motion vectors -- then these
patents are all irrelevant to VP8.

On the other hand, if Nokia *does* propose that the broad
claims of these patents cover simple motion vectors, there
is a lot of MPEG-2-era prior art that is relevant.

In other words, when searching for prior art on these
patents, we should adopt the (somewhat unlikely) hypothesis
that the term "motion model" in Nokia's patents *includes*
simple motion vectors. I expect that will make it pretty
easy to find prior art.

Listing Independent Claims per Patent
Authored by: Anonymous on Wednesday, April 03 2013 @ 03:59 PM EDT
We run a test report on our patent search tool Searcher.io, see the full results

here: http://drp.mk/mcC
I'm no domain expert, but maybe some of you can spot relevant prior art. I'm
happy to send more reports based on different pantent / claims if you think it's

useful!
