Claims 4, 43, 44, 47-52, 55---60, and 62 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Shin I, Anderson, and Shin II. Final Act. 3-9. ANALYSIS We have reviewed the Examiner's rejections in light of Appellants' arguments that the Examiner has erred. We disagree with Appellants' arguments. Appellants argue Shin I does not teach "applying an inverse transform to the multi-dimensional signal, the inverse transform interpolating parent data on a coarser scale to predict child data on a finer scale," as recited in Claim 4. App. Br. 7. Appellants contend the claimed inverse transform requires "interpolating parent data on a coarser scale to predict child data on a finer scale," as recited in the claim. Reply Br. 2. Appellants next argue the claimed phrase, "to predict child data on a finer scale," limits the claim, not indicating intended use. Id. at 2-3. The Examiner finds Shin I teaches a regularized iterative image interpolation algorithm that corresponds to the "inverse transform," as recited in the claim. Ans. 2, 3, 5 (citing Shin I § 3). The Examiner further finds Shin I teaches using low resolution image, "yi," as parent data on a coarser scale to predict child data on a finer scale in the regularized iterative image interpolation algorithm in equations (7) and (8). Ans. 3, 5, 7 (citing Shin I § 3). Although the Examiner explains that the limitation, "to predict 3 Appeal 2014-004119 Application 13/401,694 child data on a finer scale," recited in the claim is intended use and not required (Ans. 3, 6), the Examiner nevertheless finds Shin I teaches this limitation. Final Act. 4 (citing Fig. 2 ). We agree with the Examiner that the high resolution image N corresponding toxin equations (7) and (8) at least suggests the "child data on a finer scale," recited in the claim. Ans. 3 (citing Shin I § 3); Final Act. 4 (citing Shin I Fig. 2 (image NxN, x(m1,m2))). Appellants contend Shin I teaches a "process which starts at the NxN high resolution image and ends at the N/2xN/2 low resolution image." App. Br. at 8 (citing Shin I Fig. 2). Specifically, Appellants then assert the NxN high resolution image is not "child data on a finer scale," as recited in the claim. Id. The Examiner finds Shin I teaches a low resolution image processed from a high resolution image from which the high resolution image is restored from the processed low resolution image. Ans. 2-3, 7-8 (citing Shin I pp. 1591- 92, Fig. 2); see Shin I p.1590 ("This paper proposes an adaptive image sequence resolution enhancement algorithm using multiscale decomposition (MSD) based image fusion. Restored high resolution image frames with high frequency components along the direction of edges can be obtained from low resolution image frames every frames."). Specifically, the Examiner finds Shin I teaches yin equation ( 4) as a low resolution image indicated as y(n1,n2) in Figure 2. Ans. 3, 7 (citing Shin Ip. 1591, Fig. 2); see Shin Ip. 1591 ("y ... represent[s] the lexicographically ordered low resolution image."). The Examiner finds Shin I uses a regularized iterative image interpolation algorithm represented by equations (7) and (8) interpolating parent data on a coarser scale designated by y to calculate the interpolated image x. Ans. 3 (citing Shin Ip. 1592). Shin I teaches 4 Appeal 2014-004119 Application 13/401,694 equations (7) and (8) are used in a first iteration; successive approximation equation (12) is used for subsequent iterations. Ans. 7 (citing Shin Ip. 1592). The Examiner agrees with Appellants that Figure 2 in Shin I depicts creating a low resolution image (N/2xN/2, y(n1,n2)) from a high resolution image (NxN, x(m1,m2)). Ans. 8 (citing Shin I Fig. 2). However, we agree with the Examiner that Shin I teaches both creating a low resolution image from a high resolution image and restoring the high resolution image from the low resolution image. Ans. 8 (citing Shin I§§ 3, 4.2). Shin I teaches the interpolated image x as the high resolution image restored from lexicographically ordered low resolution image y. Shin I§§ 2-3. Contrary to Appellants' assertion, the Examiner finds, and we agree, the NxN high resolution image correspond to "child data on a finer scale," as recited in the claim. Ans. 3 (citing Shin I§ 3); Final Act. 4 (citing Shin I Fig. 2 (image NxN, x(m1,m2))). Appellants additionally argue Shin I teaches fusing two low-resolution frames to restore image details. App. Br. 8 (citing Shin I p. 1590). Appellants assert fusing two low-resolution frames is not an "inverse transform," as recited in the claim. App. Br. 8. The Examiner finds the multi-scale decomposition (MSD)-based image fusion in Shin I is combining images as an inverse transform or inverse action of decomposing or separating an image. Ans. 9. (citing Shin I Fig. 3); Final Act. 3--4 (citing Shin I §§ 3, 4.2). We agree with the Examiner that Shin I teaches the adaptive regularized image resolution enhancement algorithm to restore a high resolution image as an inverse transform of a transform to degrade, decompose, or separate an image into a low resolution image. Final Act. 5 Appeal 2014-004119 Application 13/401,694 3--4 (citing Shin I Fig. 3). Shin I teaches that the adaptive regularized image resolution enhancement algorithm reverses the processes of DWT, DWP, and Steerable Pyramid that degrade, decompose, or separate an image into a low resolution image to result in a high resolution image. Shin I Fig. 3. Claim 4 further recites: using an interpolation filter with data-dependent filter coefficients in performing said interpolating, wherein each filter coefficient comprises a coefficient that is scaled by an inverse of a gradient value, and wherein the gradient value is computed from a center to a value in the parent data. Appellants argue that Shin II does not teach this limitation. App. Br. 9. Specifically, Appellants assert that Shin II teaches that yTy is not a gradient value, but a diagonal matrix. App. Br. 9. Appellants further point out scaling by a value is multiplying by a scalar value. Appellants additionally assert multiplying by a matrix is distinctly different from multiplying by a scalar value. Id. The Examiner finds yTy is a gradient value because it derived from the inverse of a function of the gradient magnitude, providing a detailed explanation tracing through the equations in Shin II. Ans. 4--5, 11-12. In particular, the Examiner finds Shin II teaches that yTy is replaced by v2(iJ). Ans. 4, 10-11 (citing Shin II p.1045 (see equation 18, "where yTy represents N2 x N2 diagonal matrix whose diagonal elements takes the value of v2 (i,j).")). The Examiner finds Shin II teaches that v(iJ) is represented in equation (17) as an inverse of a function of the gradient magnitude. Id.; see Shin II (equation 17 showing inverse of function of "I grad f(i,j) I," which "represents the gradient magnitude in (14)."). This finding in Shin II at least suggests "a coefficient that is scaled by an inverse of a gradient value," as 6 Appeal 2014-004119 Application 13/401,694 recited in the claim. We agree with the Examiner that Shin II evaluates VTV, a diagonal matrix, applicable to the data as a scalar value v2(iJ) for each point (iJ) in the data in accordance with equation (17). Ans. 4, 12 (citing Shin II 1045). This teaching in Shin II at least suggests "wherein the gradient value is computed from a center to a value in the parent data," as recited in the claim. In view of the foregoing, we are not persuaded that the Examiner has erred in the rejection of Claim 4. Appellants contend Claims 43, 44, and 47--49 are patentable in view of their dependence from Claim 4. App. Br. 9. Appellants further assert Claims 50-52 and 55-57 are patentable for the same reasons as Claim 4. Id. Appellants additionally argue Claims 5 8---60 and 62 are patentable for the same reasons as Claim 4. App. Br. 1 O; see also Reply Br. 3. In view of the foregoing, we are not persuaded that the Examiner has erred in rejecting Claims 43, 44, 47-52, 55-60, and 62. DECISION The rejection of Claims 4, 43, 44, 47-52, 55---60, and 62 is AFFIRMED. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l). See 37 C.F.R. § 1.136(a)(l)(iv) (2013).
