Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Arguments
Applicant’s arguments with respect to claim(s) 1, 4-7, and 10 have been considered but are moot in view of the new grounds of rejection.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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, 4-7, and 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over He et al. (He) (US 2019/0215532) in view of Hannuksela et al. (Hannuksela) (US 2014/0168362), and further in view of in Sim et al. (Sim) (US 2018/0262762).
Regarding claim 1, He discloses a method of decoding an image with a decoding apparatus, comprising:
receiving a bitstream in which the image is encoded ([0084], an encoded picture is received at a decoder);
determining a current block included in the image (FIGs. 10 and 11, [0112], current blocks B0 and B1);
obtaining information on a residual block for the current block from the bitstream ([0107], a reference picture index is used to signal a picture for interframe prediction (i.e. image transformation and residual image generation) (see [0723] of the applicant’s originally filed specification));
generating a residual block for the current block based on the information on the residual block ([0108], prediction residuals are generated using the reference image signaled by the reference picture index);
reconstructing the current block based on the residual block to generate a reconstructed image ([0108], residuals are added to the prediction block to generate a reconstructed block); and

wherein the residual block is added to a prediction block corresponding to the residual block ([0108], The reconstructed residuals may be added back to the prediction block at 626 to form a reconstructed video block), the prediction block is generated by referring to at least one neighboring sample of the current block ([0109], [0110], spatial prediction using neighboring blocks is performed to generate a prediction block);
wherein the image processing comprises padding at least one region to the reconstructed image ([0142], [0155], padding of a reference image is performed),
wherein the padding is performed by selecting one among a plurality of padding methods ([0121], [0133], geometry or repetitive padding may be applied).
He is silent about wherein the padding is performed by selecting one among a plurality of padding methods using selection information obtained from the image processing information, and wherein the image processing information is included in a supplement enhancement information (SEI) message, wherein the plurality of padding methods comprises a first padding method which uses a same sample value for the region to be padded, and wherein the same sample value is determined based on information included in the image processing information; and wherein performing the padding comprises: identifying respective partitioning unit of a plurality of partitioning units which constitute the reconstructed current image; and performing the padding for the respective identified partitioning unit.

padded ([0017], [0037], [0038], same values may be input to all pixels in a block being padded, [0047], the padding area is filled with a preset pixel value), and wherein the same sample value
is determined based on information included in the image processing information (FIG. 1, S102
and S110, the padding pixel value is calculated based on the size of the current block, [0046],
block size information is encoded and transmitted for performing padding).

of Hannuksela for more efficient encoding/decoding.
Regarding claim 4, He discloses wherein the plurality of padding methods comprises a second padding method which uses a sample inside the reconstructed image for the region to be padded ([0122], [0136], [0148], [0149], geometry padding is performed using reconstructed pixels).
