Office Action

§102
DETAILED ACTION The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 12/05/2025 has been entered. 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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1, 12, and 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Zhong et al. (USPAPN 2014/0369555). Regarding claim 1, Zhong discloses: performing feature point analysis on a video frame sequence, to obtain feature points on each video frame in the video frame sequence (see para [43], performing motion-based tracking on every consecutive pair of video frames to obtain tracking confidence value for each frame); performing target detection on an extracted frame through a first thread based on the feature points, to obtain a target box in the extracted frame (see para [42]-[46], performing object detection on frame It based on the tracking confidence value of frame It being below a threshold, to obtain target box βt), the extracted frame being a video frame extracted in the video frame sequence with at least one frame skipped between the extracted frame and another video frame of the video frame sequence, an amount of skipping being based on a target step size (see para [42]-[46], object detection may have been skipped for frame It-1 (i.e., the frame between It and another frame It-2) if frame It-1 had a tracking confidence value above the threshold, with a skipping step size of 1 frame); performing target box tracking in a current frame through a second thread based on the feature points and the target box in the extracted frame, to obtain a result target box in the current frame (see para [42]-[46], performing motion-based tracking on frame It+1 based on the tracking confidence value of frame It and the target box βt, to obtain target box βt+1); and outputting the result target box in the current frame (see fig 12-13, displaying frames and their target boxes). Regarding claims 12 and 20, Zhong discloses everything claimed as applied above (see rejection of claim 1; and Zhong para [35], a computer). Allowable Subject Matter Claims 2-11 and 13-19 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Response to Arguments Applicant’s arguments with respect to claims 1, 12, and 20 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Seo et al. (“Effective and efficient human action recognition using dynamic frame skipping and trajectory rejection”) and Lin et al. (USPN 12,205,306) each discloses object tracking while adaptively skipping frames low in motion.
