Publication number: 20230222560Abstract: Techniques and systems are described that leverage computer vision as part of search to expand functionality of a computing device available to a user and increase operational computational efficiency as well as efficiency in user interaction. In a first example, user interaction with items of digital content is monitored. Computer vision techniques are used to identify digital images in the digital content, objects within the digital images, and characteristics of those objects. This information is used to assign a user to a user segment of a user population which is then used to control output of subsequent digital content to the user, e.g., recommendations, digital marketing content, and so forth.Type: ApplicationFiled: March 13, 2023Publication date: July 13, 2023Applicant: eBay Inc.Inventors: Robinson Piramuthu, Timothy Samuel Keefer, Ashmeet Singh Rekhi, Padmapriya Gudipati, Mohammadhadi Kiapour, Shuai Zheng, Md Atiq ul Islam, Nicholas Anthony Whyte, Giridharan Iyengar

Publication number: 20220101403Abstract: Computer vision and image characteristic search is described. The described system leverages visual search techniques by determining visual characteristics of objects depicted in images and comparing the determined characteristics to visual characteristics of other images, e.g., to identify similar visual characteristics in the other images. In some aspects, the described system performs searches that leverage a digital image as part of a search query to locate digital content of interest. In some aspects, the described system surfaces multiple user interface instrumentalities that include images of patterns, textures, or materials and that are selectable to initiate a visual search of digital content having a similar pattern, texture, or material. The described aspects also include pattern-based authentication in which the system determines authenticity of an item in an image based on a similarity of its visual characteristics to visual characteristics of known authentic items.Type: ApplicationFiled: December 14, 2021Publication date: March 31, 2022Applicant: eBay Inc.Inventors: Robinson Piramuthu, Timothy Samuel Keefer, Kenneth Clark Crookston, Ashmeet Singh Rekhi, Niaz Ahamed Khaja Nazimudeen, Padmapriya Gudipati, Shane Lin, John F.

Patent number: 11200611Abstract: Computer vision for unsuccessful queries and iterative search is described. The described system leverages visual search techniques by determining visual characteristics of objects depicted in images and describing them, e.g., using feature vectors. In some aspects, these visual characteristics are determined for search queries that are identified as not being successful. Aggregated information describing visual characteristics of images of unsuccessful search queries is used to determine common visual characteristics and objects depicted in those images. This information can be used to inform other users about unmet needs of searching users. In some aspects, these visual characteristics are used in connection with iterative image searches where users select an initial query image and then the search results are iteratively refined.Type: GrantFiled: December 28, 2018Date of Patent: December 14, 2021Assignee: eBay Inc.Inventors: Robinson Piramuthu, Timothy Samuel Keefer, Ashmeet Singh Rekhi, Padmapriya Gudipati, Mohammadhadi Kiapour, Shuai Zheng, Alberto Ordonez Pereira, Ravindra Surya Lanka, Md Atiq ul Islam, Nicholas Anthony Whyte, Giridharan Iyengar, Bryan Allen Plummer

The media descriptors from all modalities are collated and cross-linked. A query processing and presentation module, which receives queries and presents results, may also be provided. A query may consist of textual keywords from user input. Alternatively, a query may derive from a media source, such as a text document, image, audio source, or video source.Type: ApplicationFiled: August 13, 2003Publication date: February 17, 2005Applicant: International Business Machines CorporationInventors: Giridharan Iyengar, Chalapathy Neti, Harriet Nock

Publication number: 20040123231Abstract: A manual annotation system of multi-modal characteristics in multimedia files. There is provided an arrangement for selection an observation modality of video with audio, video without audio, audio with video, or audio without video, to be used to annotate multimedia content. While annotating video or audio features in isolation results in less confidence in the identification of the features, observing both audio and video simultaneously and annotating that observation results in a higher confidence level.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Inventors: Hugh W.
