Appeal No. 2002-1133
Application No. 09/186,754
BACKGROUND
Appellant's invention relates to a motion compensation performance
improvement by removing redundant edge information. An understanding of the
invention can be derived from a reading of exemplary claim 1, which is reproduced
below.
1. A preprocessor for improving motion compensation performance in
a compression encoder comprising:
means for determining a spatial shift between a current image from
an input video signal and a reference image from the input video signal,
the spatial shift having an integer value and a high precision fractional
value;
means for calculating from the high precision fractional value and
specified constants a fractional shift value; and
means for resampling the current image according to the fractional
shift value so that the current image aligns with a quantizer motion vector
grid for the compression encoder, the resampled current image being
input to the compression encoder.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:
Odaka et al. (Odaka) 5,317,397 May 31, 1994
Girod, Bernd, “Motion-Compensating Prediction with Fractional-Pel Accuracy,” 41 IEEE
Transactions on Communications no. 4, 604-612 (April 1993).
Claims 1, 2, 5 and 8 stand rejected under 35 U.S.C. § 102 as being anticipated
by Girod. Claims 3 and 6 stand rejected under 35 U.S.C. § 103 as being unpatentable
over Girod in view of Odaka.
