Appeal No. 95-4414
Application 08/143,007
a compressor for receiving and compressing the reference
image at the pre-specified level of compression;
a decompressor connected to said compressor for
decompressing the compressed reference image to produce a
processed image;
a blocking estimation processor connected to said
decompressor for receiving the reference image and said processed
image, said blocking estimation processor including means for
segmenting the reference image and said processed image each into
an array of blocks, wherein each block has an intensity
variation, and means for generating intensity variation loss
information regarding the percentage of blocks of said processed
image having less than a pre-determined fraction of the intensity
variation of a corresponding block of the reference image; and
a quality rating generator connected to said blocking
estimation processor for generating an impairment level based on
said intensity variation loss information, which level indicates
a quality rating which predicts the subjective quality of said
processed image.
The examiner relies on the following reference:
Bovik et al. (Bovik) 5,282,255 Jan. 25, 1994
(filed June 17, 1991)
Claims 1, 5 and 14 stand rejected under 35 U.S.C. § 103.
As evidence of obviousness the examiner offers Bovik taken alone.
Rather than repeat the arguments of appellant or the
examiner, we make reference to the brief and the answers for the
respective details thereof.
