Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1, 2, 6-9, 13-16, 19, 20 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Cui (“Asymmetric Gained Deep Image Compression With Continuous Rate Adaptation”, Aug 2022).
Regarding claims 1, 8, and 15, Cui teaches A method for image encoding (Cui, pg 1, column 2, first full paragraph, reproduced below:

media_image1.png
Greyscale
, “Novel image compression framework, AG-VAE” is being interpreted as involving image encoding [for claim 1] and decoding [for claims 8 and 15]), comprising:
generating a latent representation using an input image (Cui, pg 3, column 1, Section 3.1, ¶1, reproduced below:
PNG
media_image2.png
764

. “We taken one image as input of the encoder to obtain its latent representation”);
generating a quantized latent representation (Cui, pg 3, column 1, Section 3.1, ¶2-3, reproduced below:
PNG
media_image3.png
674
742
media_image3.png
Greyscale
. “Quantization loss of the latent representation” is being interpreted as involving “generating a quantized latent representation”) by performing adaptive quantization on the latent representation (Cui, pg 3, column 1, see Section 3.1, ¶2-3 image above: “scale the latent representation flexibly” is being interpreted as involving “adaptive quantization on the latent representation”);
deriving a set of selected elements of the quantized latent representation (Cui, see Section 3.1 images above for full context, but ¶1 cites: “We can conclude that the channels’ importance varies and can be scaled to control the reconstruction quality”. “Importance varies” shows a set of selected elements, the importance values. When combined with the “scale the latent representation flexibly” from ¶2 and the “quantization loss” from ¶3, shows “quantized latent representation”); and
generating encoded information of the selected elements by performing entropy encoding on the set of the selected elements (Cui, pg 1 column 2 last paragraph to pg 2 column lines1-4, reproduced below:
PNG
media_image4.png
529
1142

Greyscale
. “Asymmetric Gaussian entropy model” is being interpreted as involving entropy encoding. As the Cui framework does encoding and decoding, as see in Figure 1 text. Further. Section 3.5 shows the entropy model generates encoded information [“estimate the distribution of the latent representation”]).
Regarding claim 2, Cui teaches The method of claim 1, wherein the quantized latent representation is generated for a specific target quality level (Cui, pg 3, section 3.1, ¶1, reproduced below:
PNG
media_image5.png
804
758
media_image5.png
Greyscale
“can be scaled to control the reconstruction quality” is being interpreted to involve “a specific target quality level”).
Regarding claim 6, Cui teaches The method of claim 1, wherein the encoded information of the selected elements is generated using a parameter for a specific target quality level (Cui, section 3.1, ¶1, reproduced below:
PNG
media_image6.png
802
758
media_image6.png
Greyscale
. “can be scaled to control the reconstruction quality” is being interpreted as “a specific target quality level”. The “channels’ importance varies” is being interpreted as “a parameter”).
Regarding claim 7, Cui teaches The method of claim 6, wherein the parameter includes a scale parameter for the specific target quality level (Cui, section 3.1, ¶1, reproduced below:
PNG
media_image6.png
802
758
media_image6.png
Greyscale
. “can be scaled to control the reconstruction quality” is being interpreted as “a specific target quality level”. The “channels’ importance varies” is being interpreted as “a parameter” that can be scaled) or a mean parameter for the specific target quality level.
Claims 9 and 16 is/are rejected using the same rationale as applied to claim 2 discussed above.
Claims 13 and 19 is/are rejected using the same rationale as applied to claim 6 discussed above.
Claims 14 and 20 is/are rejected using the same rationale as applied to claim 7 discussed above.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 3, 10, 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cui, in view of Li (“Learning Convolutional Networks for Content-weighted Image Compression”, 2017).
Regarding claim 3, Cui teaches The method of claim 1, wherein the set of the selected elements (Cui, see Section 3.1 images above for full context, but ¶1 cites: “We can conclude that the channels’ importance varies and can be scaled to control the reconstruction quality”. “Importance varies” shows a set of selected elements, the importance values. When combined with the “scale the latent representation flexibly” from ¶2 and the “quantization loss” from ¶3, shows “quantized latent representation”)
However, Cui does not appear to explicitly teach 3D binary mask; though does teach importance values as the Li reference does.
Pertaining to the same field of endeavor, Li teaches
is determined using a 3D binary mask (Li, pg 4, column 2, full paragraphs 1-3, reproduced below:
PNG
media_image7.png
726
556
media_image7.png
Greyscale
. The “importance mask” with three-dimensions n x h x w, is being interpreted as involving a “3D binary mask”. Equation 5 shows the binary nature of the importance mask).
Cui and Li are considered to be analogous art because they are directed to learned image compression. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the method and system for image compression with importance values (as taught by Cui) to include a 3D binary mask (as taught by Li) because the combination provides an improvement to image compression (Li, abstract). Further, Cui teaches 3D latent representation (Cui, section 3.1, line 5).
Claims 10 and 17 is/are rejected using the same rationale as applied to claim 3 discussed above.
Claim(s) 4, 5, 11, 12, 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Cui, as modified by Li, in view of Balle (“Variational image compression with a scale hyperprior”, 2018).
Regarding claim 4, Cui teaches The method of claim 3, wherein the 3D binary mask is generated (Li, pg 4, column 2, full paragraphs 1-3, reproduced below:
PNG
media_image7.png
726
556
media_image7.png
Greyscale
. The “importance mask” with three-dimensions n x h x w, is being interpreted as involving a “3D binary mask”. Equation 5 shows the binary nature of the importance mask).
However, Cui and Li do not appear to specifically teach hyper-decoder.
Pertaining to the same field of endeavor, Balle teaches
using output of a specific layer of a hyper-decoder (Balle, pg 6, Figure 4, reproduced below:
PNG
media_image8.png
630
918
media_image8.png
Greyscale
”arithmetic decoder” is being interpreted as hyper-decoder since the right side of Figure 4 is the hyperprior model. The hyperprior model is being interpreted as outputting, note the z leading to the Q out of the specific layer from the hyperprior model at the end).
Cui, Li, and Balle are considered to be analogous art because they are directed to learned image compression. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the method and system for image compression with importance values, modified to have a 3D binary mask (as taught by Cui and Li) to include an output of a specific layer of a hyper-decoder (as taught by Balle) because the combination provides an improvement to image compression (Balle, abstract).
Regarding claim 5, Balle teaches The method of claim 4, wherein a hyperprior is input to the hyper-decoder (Balle, pg 6, Figure 4, reproduced below:
PNG
media_image8.png
630
918
media_image8.png
Greyscale
”arithmetic decoder” is being interpreted as hyper-decoder since the right side of Figure 4 is the hyperprior model. The hyperprior is input into the hyper-decoder on the right side).
Cui, Li, and Balle are considered to be analogous art because they are directed to learned image compression. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the method and system for image compression with importance values, modified to have a 3D binary mask (as taught by Cui and Li) to include the hyperprior as input to the hyper-decoder (as taught by Balle) because the combination provides an improvement to image compression (Balle, abstract).
Claims 11 and 18 is/are rejected using the same rationale as applied to claim 4 discussed above.
Claim 12 is/are rejected using the same rationale as applied to claim 5 discussed above.
