Appeal No. 2000-1499
Application No. 08/825,474
1. Apparatus for adjusting an encoding parameter of an
image encoder to optimize encoder performance comprising:
a perceptual metric generator for determining a perceptual
metric using a just noticeable difference map that represents the
fidelity of an encoded image, where said perceptual metric is
representative of a prediction as to how a human eye would
perceive a reconstructed image of said encoded image; and
an encoder parameter selector, coupled to said perceptual
metric generator, for selecting a value for said encoding
parameter in response to said perceptual metric.
The examiner relies on the following references:
Furukawa et al. 4,689,672 Aug. 25, 1987
Aravind et al. 5,214,507 May 25, 1993
Yamaoka 5,357,584 Oct. 18, 1994
Tabatabai et al. 5,686,964 Nov. 11, 1997
(filed Dec. 4, 1995)
Claims 1-4, 6-9, 11-14 and 16-18 stand rejected under
35 U.S.C. 103. As evidence of obviousness, the examiner cites
Yamaoka with regard to claims 1-3, 7, 8, 12 and 16, adding
Aravind with regard to claims 4, 9 and 14. With regard to claims
6, 11 and 18, the examiner cites Yamaoka in view of either one of
Tabatabai or Furukawa. Apparently, claims 13 and 17 are intended
to be grouped with claims 4, 9 and 14 in being rejected over
Yamaoka in view of Aravind.
Reference is made to the brief and answer for the respective
positions of appellants and the examiner.
