DETAILED ACTION
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 .
Claim Rejections - 35 USC § 102
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 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 TOKUMO et al. (US 20240054684 A1).
Regarding claim 1. TOKUMO discloses A mesh decoding device comprising a circuit (abstract, A 3D data decoding apparatus for decoding 3D coded data includes an image decoder configured to decode the 3D coded data into a mesh displacement image) that:
outputs a base mesh (figure 3 unit 303, figure 4),
outputs an intra prediction residual (figure 3 unit 305, figure 5, [0066] the mesh displacement decoder 305 may further include an image decoder 3051; [0100] The image decoder 3051 decodes the mesh displacement image coding stream coded in VVC, HEVC, or the like, and outputs a decoded image having pixel values of quantized mesh displacement (mesh displacement image, mesh displacement array); [0120] In the image decoder 3051, typically, an intra-prediction method or an inter-prediction method is used (inherently, an intra-prediction residual of a mesh displacement image is output within the image decoder 3051 when an intra-prediction method is used)), and
decodes a displacement by performing intra prediction of a displacement of a subdivided vertex based on the outputted base mesh to calculate an intra prediction value, and adding the calculated intra prediction value and the outputted intra prediction residual ([0111] The disp represents a three-dimensional vector indicating a mesh displacement after coordinate system conversion, and is a Cartesian coordinate system. n_vec, t_vec, and b_vec represent three-dimensional vectors (of a Cartesian coordinate system) corresponding to respective axes of the local coordinate system of the target region or target vertex; figure 12 unit 115, figure 15 units 1152 and 1153, [0146] The mesh subdivision unit 1152 subdivides the base mesh to generate a subdivided mesh like the mesh subdivision unit 3071 (FIG. 16(c)), [0143]; figure 3 unit 305, figure 5, [0066] the mesh displacement decoder 305 may further include an image decoder 3051; [0100] The image decoder 3051 decodes the mesh displacement image coding stream coded in VVC, HEVC, or the like, and outputs a decoded image having pixel values of quantized mesh displacement (mesh displacement image, mesh displacement array); [0120] In the image decoder 3051, typically, an intra-prediction method or an inter-prediction method is used (inherently, an intra-prediction residual of mesh displacement image is added to an intra prediction value to obtain the displacement within the image decoder 3051 when an intra-prediction method is used in VVC, HEVC, or the like)).
Regarding claim 2. TOKUMO discloses The mesh decoding device according to claim 1, wherein
the circuits decodes the displacement based on normal vectors of points at both ends of the subdivided vertex (figure 11, [0124] v1, v2, and v3 are three-dimensional vectors. The mesh subdivision unit 3071 adds new vertices v12, v13, and v23 to intermediates of respective sides of the triangle to generate and output a subdivided mesh (FIG. 11(b)). v12=(v1+v2)/2, v13=(v1+v3)/2, v23=(v2+v3)/2; figure 16, [0146] The mesh subdivision unit 1152 subdivides the base mesh to generate a subdivided mesh like the mesh subdivision unit 3071 (FIG. 16(c)). v4′=(v1+v2)/2, v5′=(v1+v3)/2, v6′=(v2+v3)/2; [0070] Local coordinate system: an orthogonal coordinate system defined per region or vertex in the 3D space. Specifically, this is an orthogonal coordinate system consisting of a first axis (D), a second axis (U), and a third axis (V), the first axis (D) being indicated by a normal vector n_vec at a vertex (or a surface including a vertex). n_vec, t_vec, and b_vec are three-dimensional vectors).
Regarding claim 3. TOKUMO discloses The mesh decoding device according to claim 1, wherein
the circuit decodes the displacement based on a decoded displacement of the subdivided vertex (figure 12 unit 115, figure 15 units 1152 and 1153, [0146] The mesh subdivision unit 1152 subdivides the base mesh to generate a subdivided mesh like the mesh subdivision unit 3071 (FIG. 16(c)), [0143]; figure 3 unit 305, figure 5, [0066] the mesh displacement decoder 305 may further include an image decoder 3051; [0100] The image decoder 3051 decodes the mesh displacement image coding stream coded in VVC, HEVC, or the like, and outputs a decoded image having pixel values of quantized mesh displacement (mesh displacement image, mesh displacement array)).
Regarding claim 4. The same analysis has been stated in claim 1.
Furthermore, TOKUMO discloses
performing inverse quantization on a quantized intra prediction residual (figure 3 unit 305, figure 5, [0066] the mesh displacement decoder 305 may further include an image decoder 3051; [0100] The image decoder 3051 decodes the mesh displacement image coding stream coded in VVC, HEVC, or the like, and outputs a decoded image having pixel values of quantized mesh displacement (mesh displacement image, mesh displacement array); [0120] In the image decoder 3051, typically, an intra-prediction method or an inter-prediction method is used (inherently, an intra-prediction residual of mesh displacement image is first inverse quantized and then added to an intra prediction value to obtain the displacement within the image decoder 3051 when an intra-prediction method is used)).
Regarding claim 5. The same analysis has been stated in claim 1.
