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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 1-2, 5-8, 9, 11-12, 15-18 and 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ma et al. (U.S. 2022/0007015), hereinafter Ma in view of Wang et al. ("EE1-1.2: Neural Network Based In-loop Filter with a Single Model", JVET-Z0091, 20-29 April 2022, hereinafter Wang and further in view of Park et al. (U.S. 2020/0120340), hereinafter Park. Wang was cited in the Applicant’s IDS dated 5/22/24.
Regarding claims 1 and 11, Ma discloses an apparatus configured to code video data, the apparatus comprising:
a memory configured to store a picture of video data (Ma [0031] and [0171]); and
processing circuitry in communication with the memory (Ma [0171]), the processing circuitry configured to:
receive the picture of video data (Ma fig. 1, #106);
reconstruct a block of the picture of video data to generate a reconstructed block (Ma [0030]); and
perform a neural network (NN)-based filter process on the reconstructed block to generate a filtered block (Ma [0037]), the NN-based filter process using reconstruction samples of the block, prediction samples of the block, and supplementary data related to the block as inputs (Ma [0037], figs. 1 and 2).
Ma does not explicitly disclose wherein the NN-based filter process includes an initial processing of one or more types of the supplementary data with fewer computations relative to the initial processing of the reconstruction samples and the prediction samples.
However, Wang teaches receiving a picture of video data (Wang p. 2, fig. 2) and wherein the NN-based filter process includes an initial processing of one or more types of the supplementary data with fewer computations relative to the initial processing of the reconstruction samples and the prediction samples (Wang fig. 2).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Ma’s method with the missing limitations as taught by Wang to provide a neural network filter with constrained memory size and lower complexity to achieve a good trade-off between performance and complexity (Wang p. 6, section 4).
As shown above, all of the limitations are known, they can be applied to a known device such as a processor to yield a predictable result of creating a less complex neural network filtering system.
Ma does not explicitly disclose wherein the initial processing of the one or more types of the supplementary data includes a 1x1 convolution.
However, Park teaches wherein the initial processing of the one or more types of the supplementary data includes a 1x1 convolution (Park [0162] and fig. 6B).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught by Ma in view of Wang with the missing limitations as taught by Park to maintain the initial information and have a smaller error (Park [0162]).
Regarding claims 2 and 12, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11, wherein the initial processing of the reconstruction samples and the prediction samples includes a 3x3 convolution, and wherein the initial processing of the one or more types of the supplementary data includes fewer computations than the 3x3 convolution (Wang p. 2, fig. 2).
The same motivation for claim 1 applies to claims 2 and 12.
Regarding claims 5 and 15, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11, wherein the one or more types of the supplementary data include one or more of a quantization parameter (QP), partitioning information, coding mode identification, or a boundary strength (BS) for a deblocking filter (Wang fig. 2).
The same motivation for claim 1 applies to claims 5 and 15.
Regarding claims 6 and 16, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11. Ma does not explicitly disclose wherein the initial processing of the one or more types of the supplementary data includes performing a feature map derivation for a first type of the supplementary data that has a static value for the block.
However, Park further teaches, wherein the initial processing of the one or more types of the supplementary data includes performing a feature map derivation for a first type of the supplementary data that has a static value for the block (Park [0158], [0162] and fig. 6B).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught by Ma in view of Wang and Park with the missing limitations as taught by Park to maintain the initial information and have a smaller error (Park [0162]).
Regarding claims 7 and 17, Ma in view of Wang and Park teaches the method and apparatus of claims 6 and 16, wherein the feature map derivation includes a single 1x1 convolution and a value replication process (Park [0162] and fig. 6B).
The same motivation for claim 6 applies to claims 7 and 17.
Regarding claims 8 and 18, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11, wherein the initial processing of the one or more types of the supplementary data includes performing a replication of a value of a first type of the supplementary data that has a static value for the block without performing a convolution on the first type of the supplementary data (Park [0162] and fig. 6B).
The same motivation for claim 6 applies to claims 8 and 18.
Regarding claims 9 and 19, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11, wherein the apparatus is configured to decode video data and wherein the apparatus further comprises: use a decoded picture that includes the filtered block as reference for prediction in other encoded pictures (Ma [0030], figs. 1 and 2).
Claim(s) 3 and 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ma in view of Wang and Park as applied to claims 1 and 11 above, and further in view of Nash et al. (U.S. 2024/0104785), hereinafter Nash.
Regarding claims 3 and 13, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11. Ma does not explicitly disclose wherein the one or more types of the supplementary data have a sparse representation relative to the reconstruction samples and the prediction samples.
However, Nash teaches, wherein the one or more types of the supplementary data have a sparse representation relative to the reconstruction samples and the prediction samples (Nash [0064]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught by Ma in view of Wang and Park with the missing limitations as taught by Nash to significantly reduce the time, memory and computational costs required to generate synthetic images (Nash [0037]).
Claim(s) 10 and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ma in view of Wang and Park as applied to claims 1 and 11 above, and further in view of Ding et al. (U.S. 2022/0385896), hereinafter Ding.
Regarding claims 10 and 20, Ma in view of Wang and Park teaches the method and apparatus of claims 1 and 11, wherein the apparatus is configured to encode video data (Ma [0030] and fig. 1). Ma does not explicitly disclose wherein the apparatus further comprises: a camera configured to capture the picture of video data.
However, Ding teaches wherein the apparatus further comprises: a camera configured to capture the picture of video data (Ding [0071]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method taught by Ma in view of Wang and Park with the missing limitations as taught by Ding to create a stream of uncompressed images for video coding (Ding [0071]).
Response to Arguments
