Patent number: 11676412Abstract: Systems, devices, and methods are presented for segmenting an image of a video stream with a client device by receiving one or more images depicting an object of interest and determining pixels within the one or more images corresponding to the object of interest. The systems, devices, and methods identify a position of a portion of the object of interest and determine a direction for the portion of the object of interest. Based on the direction of the portion of the object of interest, a histogram threshold is dynamically modified for identifying pixels as corresponding to the portion of the object of interest. The portion of the object of interest is replaced with a graphical interface element aligned with the direction of the portion of the object of interest.Type: GrantFiled: September 16, 2020Date of Patent: June 13, 2023Assignee: Snap Inc.Inventors: Victor Shaburov, Yurii Monastyrshyn, Oleksandr Pyshchenko, Sergei Kotcur

Publication number: 20230079136Abstract: A messaging system performs neural network hair rendering for images provided by users of the messaging system. A method of neural network hair rendering includes processing a three-dimensional (3D) model of fake hair and a first real hair image depicting a first person to generate a fake hair structure, and encoding, using a fake hair encoder neural subnetwork, the fake hair structure to generate a coded fake hair structure. The method further includes processing, using a cross-domain structure embedding neural subnetwork, the coded fake hair structure to generate a fake and real hair structure, and encoding, using an appearance encoder neural subnetwork, a second real hair image depicting a second person having a second head to generate an appearance map. The method further includes processing, using a real appearance renderer neural subnetwork, the appearance map and the fake and real hair structure to generate a synthesized real image.Type: ApplicationFiled: November 15, 2022Publication date: March 16, 2023Inventors: Artem Bondich, Menglei Chai, Oleksandr Pyshchenko, Jian Ren, Sergey Tulyakov

Patent number: 11551425Abstract: Systems, devices, media, and methods are presented for presentation of modified objects within a video stream. The systems and methods receive a set of images within a video stream and identify at least a portion of a face in a first subset of images. The systems and methods determine face characteristics by analyzing the portion of the face in the first subset of images. The systems and methods apply a graphical representation of glasses to the face based on the face characteristics and cause presentation of a modified video stream including the portion of the face with the graphical representation of the glasses in a second subset of images of the set of images while receiving the video stream.Type: GrantFiled: December 8, 2020Date of Patent: January 10, 2023Assignee: Snap Inc.Inventors: Fedir Poliakov, Oleksandr Pyshchenko

Patent number: 11543929Abstract: Systems, devices, media, and methods are presented for controlling user interface with an object depicted within the user interface. The systems and methods initiates an augmented reality mode configured to present augmented reality elements within a graphical user interface. A face is detected within a field of view of an image capture component and presented within the graphical user interface. In response to detecting the face, the systems and methods sequentially present a set of augmented reality elements within the graphical user interface. A subset of the augmented reality elements and the face may be depicted contemporaneously. A movement is detected of at least a portion of the face relative to a first augmented reality element and presentation of the first augmented reality element is modified and at least one second augmented reality element is presented.Type: GrantFiled: April 6, 2021Date of Patent: January 3, 2023Assignee: Snap Inc.Inventors: Yurii Monastyrshyn, Oleksandr Pyshchenko
