Office Action

§102
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 . Status of claims: claims 1-9 and 17-20 are examined below. Claims 10-16 are withdrawn from examination. Response to Arguments Applicant's arguments filed 4/21/2026 have been fully considered but they are not persuasive. Applicant remark – (pages 8-9) Applicant argued the lack of teaching regarding screening as well as target data distribution for the selected plurality of objects. Please see Remarks for detail. Examiner response – Examiner respectfully disagree. Perry et al (US 2016/0292836) address screening by deleting as claimed in claim 1 and further detail by a first condition in claim 2 of the instant invention. Perry et al address screening/deleting of a target object of claim 2 in paragraph 0187 and 0100-0101, where the combination of threshold and target data distribution by Perry et al’s teaching of mean (0.5 w, 0.5 h) and standard deviation (0.28 w, 0.26 h) where w and h are the width and the height of the target and its position bias map 541 (distance), where mean and standard deviation reflect the data distribution. The machine learning is trained based on extracted original image data with sub-aspect of the image for detail, and presence or absence of artefacts. The function of extraction further refines by sub-aspect of the image present the target data distribution to train the machine learning. Examiner advise the claim amendment with objected claim language to advance the prosecution. 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 1-2, 7 and 17-18 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Perry et al (US 2016/0292836).

Jetley et al (US 2017/0308770) teaches END-TO-END SALIENCY MAPPING VIA PROBABILITY DISTRIBUTION PREDICTION - predicting saliency in an image and method of use of the prediction system are described. Attention maps for each of a set of training images are used to train the system. The training includes passing the training images though a neural network and optimizing an objective function over the training set which is based on a distance measure computed between a first probability distribution computed for a saliency map output by the neural network and a second probability distribution computed for the attention map for the respective training image (abstract).
