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 .
Information Disclosure Statement
The information disclosure statements (IDS) were submitted on 01/08/2025 and 02/20/2025. The submission are in compliance with the provisions of 37 CFR § 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
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)(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.
Claims 1-5 are rejected under 35 U.S.C. 102(a) (2) as being anticipated by RONDAO et al. (US 20250259335, hereinafter RONDAO).
Regarding Claim 1, RONDAO discloses a mesh decoding device ([0104], FIG. 7, a decoder using three video components, the mesh representation) comprising:
a circuit that decodes a displacement bit stream to generate and output a displacement ([0104], FIG. 7, decoder using three video components, the mesh representation (per frame) consists in three Video Components {geometry components, occupancy components, and a displacement field,[0009]} that are all independently encoded using a video codec such as HEVC or VVC) , wherein the circuit:
outputs a video by decoding the displacement bit stream by video encoding ([0111] apply decoded displacements (for example represented by a new V3C Transform Attribute type) on the decoded base mesh to perform the inverse quantization, inverse wavelet transform and subdivision scheme),
develops and outputs the video as a level value for each image ([0140], input the reconstructed base mesh for the subdivision module that splits base mesh faces into four faces by using mid-point subdivision for example, sets the maximal level of subdivisions to be performed and compute distance field vectors using the subdivided base mesh and the input mesh),
generates a transformed coefficient by inversely quantizing the level values ([0109]-[0111], metadata describes information required to decode the base mesh to perform the inverse quantization), and
generates the displacement by applying an inverse wavelet transform to the transformed coefficient ([0111]-[0112], perform the inverse wavelet transform and subdivision scheme used to apply decoded displacements and convert the Texture Attribute Map to the desired color format/space).
Regarding Claim 2, RONDAO discloses the mesh decoding device according to claim 1, wherein the video decoding unit is configured to output a video by performing decoding using a video coding method in which a motion vector is constantly zero ([0106] A displacement field bitstream that contains wavelet encoded and quantized position displacements or error vectors; [0140], at full mesh decoder side, the same values from reconstructed base mesh may be used, as in the full mesh encoder, to compute predictions and displacements.
Each frame as an independent displacement map, preventing temporal prediction from altering the spatial data - performing decoding using a video coding method in which a motion vector is constantly zero.
Regarding Claim 3, RONDAO discloses the mesh decoding device according to claim 1, wherein the video decoding unit is configured to output a video by performing decoding using a video coding method in which conversion is constantly skipped ([0140], packing the quantized wavelet coefficients into a Video Component with a wavelet transform which is identity transform. When the wavelet transform is identity, the "level values" from the video decoder map directly to the reconstructed displacement after inverse quantization due to the effect of direct mapping).
Regarding Claim 4, Method claim 4 of using the corresponding device claimed in claims 1, and the rejections of which are incorporated herein for the same reasons n as used above.
Regarding Claim 5, Computer- readable medium claim 5 of using the corresponding device claimed in claims 1, and the rejections of which are incorporated herein for the same reasons n as used above.
