Abstract: Among other things, embodiments of the present disclosure improve the functionality of electronic messaging software and systems by automatically analyzing media content associated with a user and generating collections of such content (e.g., “stories”) based on varying criteria.

Abstract: A social network image pool system can capture one or more image data items (e.g., image, video) in a temporary persistent post pool. The post pool enables for efficient capture of multiple image data items for publishing in a manner that allows multiple images data items to be captured while preserving the editability of the multiple items before they are published to a social network site.

Abstract: Embodiments described herein include an expressive icon system to present an animated graphical icon, wherein the animated graphical icon is generated by capture facial tracking data at a client device. In some embodiments, the system may track and capture facial tracking data of a user via a camera associated with a client device (e.g., a front facing camera, or a paired camera), and process the facial tracking data to animate a graphical icon.

Abstract: Systems and methods provide for advanced video editing techniques using sampling patterns. In one example, a computing device can receive a selection of a clip of a video and a sampling pattern. The computing device can determine a respective number of frames to sample from the clip for each interval of time over a length of time for a new clip. For example, the computing device can determine a function corresponding the pattern that relates time and the number of frames to sample, a histogram corresponding to the pattern, or a definite integral corresponding to the pattern, among other approaches. The computing device can extract these numbers of frames from the clip and generate the new clip from the extracted frames. The computing device can present the new clip as a preview and send the new clip to other computing devices.

Abstract: Embodiments of the present disclosure relate generally to systems for enhancing a first media item through the addition of a supplemental second media item. A user may provide a request to enhance a selected media item, and in response, an enhancement system retrieves and presents a curated collection of supplemental content to be added to the media, to the user. The user may review the curated collection of supplemental content, for example by providing a tactile input to scroll through the curated collection of content.

Abstract: Among other things, the functionality of electronic messaging software and systems is improved by automatically analyzing media content associated with a user and generating collections of such content (e.g., “stories”) based on varying criteria. For example, a narrative group criterion stored in a database in communication with the system is selected, a media content item associated with the narrative . roup criterion and associated. with a user is selected, a media content collection comprising the selected media content item is generated, and the media content collection is displayed on a display screen of a computing device of the user.

Abstract: Systems and methods for presenting an augmented reality within a custom graphic are provided. In example embodiments, one or more hardware processors may receive an image, identify candidate shape features in the image, identify a custom graphic by comparing the candidate shape features with a reference shape feature of the custom graphic, identify an optical barcode based on the identified custom graphic, identify an augmented reality based on the optical barcode, and transmit the augmented reality to the client device.

Abstract: A system and method for presentation of computer vision (e.g., augmented reality, virtual reality) using user data and a user code is disclosed. A client device can detect an image feature (e.g., scannable code) in one or more images. The image feature is determined to be linked to a user account. User data from the user account can then be used to generate one or more augmented reality display elements that can be anchored to the image feature in the one or more images.

Abstract: Embodiments for communicating and displaying collections of image and video clip content with an opt-out interstitial are described. In one example embodiment, a device receives interface information about a group of content collections from a server computer system. When a user inputs a selection of a first content collection, the device displays images and video clips in a sequence defined by the content collection. Each piece of content is displayed for less than a threshold display time. When the device finishes playing the first content collection, the device presents an opt-out interstitial. Additional content collections generated from content submitted by other client devices can be received from the server computer system, and are presented based on a response input, or a lack of response input, to the opt-out interstitial. Some embodiments include content collections generated by the server computer system, as well as advertising elements presented between content collections.
