Publication number: 20190295326Abstract: Systems and methods for image based location estimation are described. In one example embodiment, a first positioning system is used to generate a first position estimate. A set of structure façade data describing one or more structure façades associated with the first position estimate is then accessed. A first image of an environment is captured, and a portion of the image is matched to part of the structure façade data. A second position is then estimated based on a comparison of the structure façade data with the portion of the image matched to the structure façade data.Type: ApplicationFiled: June 11, 2019Publication date: September 26, 2019Inventors: Nathan Jurgenson, Linjie Luo, Jonathan M. Rodriguez, II, Rahul Sheth, Jia Li, Xutao Lv

Patent number: 10395100Abstract: Systems, devices, media, and methods are presented for modeling facial representations using image segmentation with a client device. The systems and methods receive an image depicting a face, detect at least a portion of the face within the image, and identify a set of facial features within the portion of the face. The systems and methods generate a descriptor function representing the set of facial features, fit object functions of the descriptor function, identify an identification probability for each facial feature, and assign an identification to each facial feature.Type: GrantFiled: December 19, 2018Date of Patent: August 27, 2019Assignee: Snap Inc.Inventors: Jia Li, Xutao Lv, Xiaoyu Wang, Xuehan Xiong, Jianchao Yang

Patent number: 9984499Abstract: Systems and methods for image based location estimation are described. In one example embodiment, a first positioning system is used to generate a first position estimate. A 3D point cloud data describing an environment is then accessed. A first image of an environment is captured, and a portion of the image is matched to a portion of key points in the 3D point cloud data. An augmented reality object is then aligned within one or more images of the environment based on the match of the 3D point cloud with the image. In some embodiments, building façade data may additionally be used to determine a device location and place the augmented reality object within an image.Type: GrantFiled: November 30, 2015Date of Patent: May 29, 2018Assignee: Snap Inc.Inventors: Nathan Jurgenson, Linjie Luo, Jonathan M Rodriguez, II, Rahul Sheth, Jia Li, Xutao Lv

Publication number: 20170357878Abstract: A computing system and method for identifying related visual content of a collection of visual media files comprising one or more image files and video files includes monitoring inputs to the computing system, the inputs associated with a user interaction with electronic content using the computer system, identifying a visual media file in the collection of visual media files relevant to the electronic content based on a semantic label assigned to the visual media file by the computing system, creating a representative image of the identified visual media file, and displaying the representative image for selection. The computing system enables a selection of the displayed representative image for association of the identified visual media file with the electronic content.Type: ApplicationFiled: July 20, 2017Publication date: December 14, 2017Inventors: Harpreet Singh Sawhney, Jayakrishnan Eledath, Mayank Bansal, Bogdan C.
