Publication number: 20240153209Abstract: An object reconstruction method includes obtaining a plurality of target images and real poses corresponding to a case in which a camera captures the target images. Based on the target images and the real poses, a sparse point cloud whose size is consistent with a real size of a target object is constructed and a three-dimensional (3D) model of the target object is generated based on the sparse point cloud. A distribution size of the sparse point cloud generated based on the first poses is consistent with the real size of the target object such that the reconstructed 3D model is more realistic, and does not include a size distortion.Type: ApplicationFiled: January 12, 2024Publication date: May 9, 2024Inventors: Ziya Xu, Xu Cheng, Wenchao Sun

Patent number: 11947586Abstract: Techniques are disclosed for automatic scene detection and character extraction. In one example, audiovisual content with video frames, an audio recording, and timing information is received. A score, based on the frame's visual characteristics, is determined for a first frame and subsequent frames. The first frame's score and subsequent frame's scores are compared to determine if the difference between the scores is above a threshold. When the difference in scores is above a threshold, the subsequent frame is classified as a new scene. The audiovisual content is segmented into scenes and textual characters are identified in at least one frame from each scene. The characters are stored and indexed in a searchable database with the timing information for the scene where the characters were identified. The audio recording is transcribed and the transcribed words are stored and indexed in the searchable database with timing information.Type: GrantFiled: November 22, 2021Date of Patent: April 2, 2024Assignee: Oracle International CorporationInventors: Wenchao Sun, Dru Kingston Borden, Tsz-Yam Lau, Shi-Rong Chang

Publication number: 20220114803Abstract: A method includes obtaining, by a camera, a current image, determining a pattern of the target object in the current image, determining, based on the pattern of a target object in the current image, whether a three-dimensional model of the target object is reconstructible, and displaying first prompt information on a display in response to determining that the three-dimensional model of the target object is reconstructible. The current image is at least one of a plurality of frames of images of the target object. The first prompt information is usable to indicate that the three-dimensional model of the target object is reconstructible.Type: ApplicationFiled: December 20, 2021Publication date: April 14, 2022Inventors: Guoyi WANG, Bing CHEN, Wenchao SUN, Ziya XU

Publication number: 20200050942Abstract: An example system and method facilitate enabling precise answers to technical support questions pertaining to a given computing environment, e.g., a cloud-based enterprise computing environment. The example method includes using an overtrained recurrent neural network employing Long Short-Term Memory (LSTM) cells to selectively answer specific questions by providing precise answers to technical support questions. A second neural network that is not overtrained can provide more generalized answers when a confidence measurement of an answer of the first neural network falls below a predetermined threshold. Furthermore, expert staff, e.g., developers and/or engineers that may be able to more precisely answer a specific question may be shown the answer. Subsequent expert answers or modifications to existing answers may be used to further refine the neural networks, e.g., via periodic supervised learning.Type: ApplicationFiled: August 7, 2018Publication date: February 13, 2020Applicant: Oracle International CorporationInventors: Wenchao Sun, Zhengrong Liu
