Appeal No. 1999-2825
Application 08/967,251
Representative claim 1 is reproduced as follows:
1. A heuristic based motion estimation method for video
compression, said method comprising the steps of:
defining a target block in a video clip;
defining a simplified signature block from said target
block, said simplified signature block being based on a row and
column sum of pixels only within said target block;
searching a reference frame using said simplified
signature block;
searching for a best match in an area centered around
said target block in said reference frame using said simplified
signature block;
computing a sum of an absolute pixel-by-pixel difference
using motion vectors of said area and a zero motion vector;
selecting a new block with a motion vector with a minimum
sum of said absolute pixel-by-pixel difference; and
searching a new area centered around said new block for a
minimum absolute difference match.
The examiner relies on the following reference:
Kondo et al. (Kondo) 5,453,800 Sep. 26, 1995
Claims 1-9 stand rejected under 35 U.S.C. § 102(e) as
being anticipated by the disclosure of Kondo.
Rather than repeat the arguments of appellant or the
examiner, we make reference to the brief and the answer for the
respective details thereof.
