Publication number: 20230360254Abstract: A pose estimation method and an apparatus are provided, to obtain a more accurate pose estimation result. The method includes: obtaining a first event image and a first target image, where the first event image is aligned with the first target image in time sequence, the first target image includes an RGB image or a depth image, and the first event image includes an image indicating a movement trajectory that is of a target object and that is generated when the target object moves in a detection range of a motion sensor; determining integration time of the first event image; if the integration time is less than a first threshold, determining that the first target image is not for performing pose estimation; and performing pose estimation based on the first event image.Type: ApplicationFiled: June 29, 2023Publication date: November 9, 2023Inventors: Chang LIU, Chuangchuang LIU, Baoyang CHEN, Yuntan FANG, Siwei DONG, Shu FANG, Huimin ZHANG

Publication number: 20230325999Abstract: This application discloses an image generation method and apparatus, and an electronic device, and relates to the field of image processing. The method includes: acquiring a spectrum image of a first scene by using a first camera that supports more photosensitive bands than a second camera, and acquiring a color image of a second scene by using a second camera, where both the color image and the spectrum image include a same target object; then, correcting a color cast of a reconstructed spectrum image of the color image based on the spectrum image, to acquire a plurality of corrected reconstructed spectrum images; and fusing the plurality of corrected reconstructed spectrum images to generate a corrected color image whose color is closer to a color of the second scene than a color of the color image.Type: ApplicationFiled: June 15, 2023Publication date: October 12, 2023Inventors: Siwei DONG, Hui YANG, Baoyang CHEN, Jia HU

Patent number: 11620349Abstract: Systems, methods, and non-transitory computer-readable media can determine respective engagement scores for one or more users based at least in part on their engagement with a plurality of content items associated with an entity in a content provider system. At least one user who is a top fan of the entity can be determined based at least in part on the determined engagement scores. The user can be associated with a visual badge in the content provider system to identify the user as a top fan of the entity, wherein the visual badge is made visible by the content provider system to at least the entity.Type: GrantFiled: March 25, 2020Date of Patent: April 4, 2023Assignee: Meta Platforms, Inc.Inventors: Hongzheng Xiong, Ashish Gupta, Vamsi Krishna Cheekatimalla, Siwei Dong, Omer Shahid

Publication number: 20230098678Abstract: A speech signal processing method and a related device thereof are provided. The method may be applied to the audio field and includes: obtaining a user speech signal captured by a sensor; obtaining a corresponding vibration signal when a user generates a speech, where the vibration signal indicates a vibration feature of a body part of the user, and the body part is a part that vibrates correspondingly based on sound-making behavior when the user is making a sound; and obtaining target speech information based on the vibration signal and the user speech signal captured by the sensor. In this application, the vibration signal is used as a basis for speech recognition.Type: ApplicationFiled: November 28, 2022Publication date: March 30, 2023Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Libin Zhang, Hui Yang, Shu Fang, Siwei Dong
