Patent number: 11336972Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for automated video preview generation. Example methods may include determining video content, determining a first shot transition, a second shot transition, a third shot transition, and a fourth shot transition in the video content, and determining that human speech is present during the first shot transition and the second shot transition. Example methods may include determining a first timestamp associated with the third shot transition, determining a second timestamp associated with the fourth shot transition, generating a first video preview of the video content, where the first video preview includes a segment of the video content from the first timestamp to the second timestamp, and causing presentation of the first video preview, where the first video preview does not include a segment of the video content between the first shot transition and the second shot transition.Type: GrantFiled: January 5, 2021Date of Patent: May 17, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Muhammad Raffay Hamid, Kewen Chen, Anne TuAnh Thanh Thuy Ho, Guy Friedel, Arun Velayudhan Pillai, Dhaval Damani, Jacob William Jensen, Zuzanna Maria Stepniakowska Coggins, Maciej Tadeusz Golonka, Anantha Krishna Hodrali Srinivasa Bhatta

Publication number: 20220084222Abstract: Methods and systems are described for registering a sports field to a video. Video of a live event may feature participants at a venue. A template of the venue, including virtual markings that represent real markings on the venue, may be obtained. A homographic transformation between an image plane and a ground plane may be determined by matching virtual markings to corresponding real markings captured in at least one frame of the video. The determined homographic transformation may be used in the automated analysis of sports statistics and in improving inserted annotations and visualizations.Type: ApplicationFiled: September 14, 2020Publication date: March 17, 2022Inventors: Xiaohan Nie, Muhammad Raffay Hamid

Patent number: 11205445Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for language agnostic automated voice activity detection. Example methods may include determining an audio file associated with video content, generating a number of audio segments using the audio file, the plurality of audio segments including a first segment and a second segment, where the first segment and the second segment are consecutive segments. Example methods may include determining, using a Gated Recurrent Unit neural network, that the first segment includes first voice activity, determining, using the Gated Recurrent Unit neural network, that the second segment includes second voice activity, and determining that voice activity is present between a first timestamp associated with the first segment and a second timestamp associated with the second segment.Type: GrantFiled: June 10, 2019Date of Patent: December 21, 2021Assignee: Amazon Technologies, Inc.Inventors: Mayank Sharma, Sandeep Joshi, Muhammad Raffay Hamid

Patent number: 11151386Abstract: Systems, methods, and computer-readable media are disclosed for systems and methods for automated identification and tagging of video content. Example methods may include determining a first set of frames in video content, determining a first set of faces that appear in the first set of frames, and extracting first image content corresponding to respective faces of the first set of faces. Methods may include classifying the first image content into a first set of clusters, generating a second set of clusters comprising a second set of faces, wherein the second set of faces has less faces than the first set of faces, and determining a first actor identifier associated with a first face in the second set of clusters. Some methods may include determining second image content in the second set of clusters comprising the first face, and automatically associating the first actor identifier with the second image content.Type: GrantFiled: March 4, 2020Date of Patent: October 19, 2021Assignee: Amazon Technologies, Inc.Inventors: Abhinav Aggarwal, Heena Bansal, Lokesh Amarnath Ravindranathan, Yash Pandya, Muhammad Raffay Hamid, Manivel Sethu

Patent number: 10945041Abstract: Devices, systems, and methods are provided for language-agnostic subtitle drift detection and localization. A method may include extracting audio from video, dividing the audio into overlapping blocks, and determining the probabilities of overlapping portions of the blocks, the probabilities indicating a presence of voice data represented by the audio in the blocks. The method may generate machine blocks using overlapping portions of blocks where voice data is present, and may map the machine blocks to corresponding blocks indicating that subtitles are available for the video. For mapped blocks, the method may include determining features such as when subtitles are available without voice audio, when voice audio is available without subtitles, and when voice audio and subtitles both are available. Using the features, the method may include determining the probability that the video includes subtitle drift, and the method may include analyzing the video to localize where the subtitle drift occurs.Type: GrantFiled: June 2, 2020Date of Patent: March 9, 2021Assignee: Amazon Technologies, Inc.Inventors: Tamojit Chatterjee, Mayank Sharma, Muhammad Raffay Hamid, Sandeep Joshi

Patent number: 9886653Abstract: An apparatus and method for obtaining image feature data of an image are disclosed herein. A color histogram of the image is extracted from the image, the extraction of the color histogram including performing one-dimensional sampling of pixels comprising the image in each of a first dimension of a color space, a second dimension of the color space, and a third dimension of the color space. An edge map corresponding to the image is analyzed to detect a pattern included in the image. In response to a confidence level of the pattern detection being below a pre-defined threshold, extracting from the image an orientation histogram of the image. And identify a dominant color of the image.Type: GrantFiled: January 6, 2016Date of Patent: February 6, 2018Assignee: eBay Inc.Inventors: Anurag Bhardwaj, Wei Di, Muhammad Raffay Hamid, Robinson Piramuthu, Neelakantan Sundaresan
