Abstract: Systems and methods are provided for performing operations including: receiving, via a messaging application, input that selects a collection of augmented reality items; obtaining an identifier of the collection of the augmented reality items; searching, based on the identifier, a plurality of augmented reality items to identify a subset of augmented reality items associated with the identifier; causing the messaging application to present the subset of augmented reality items; and causing the messaging application to modify an image based on a first augmented reality item in the subset.

Abstract: Systems, devices, media, and methods are presented for object detection and inserting graphical elements into an image stream in response to detecting the object. The systems and methods detect an object of interest in received frames of a video stream. The systems and methods identify a bounding box for the object of interest and estimate a three-dimensional position of the object of interest based on a scale of the object of interest. The systems and methods generate one or more graphical elements having a size based on the scale of the object of interest and a position based on the three-dimensional position estimated for the object of interest. The one or more graphical elements are generated within the video stream to form a modified video stream. The systems and methods cause presentation of the modified video stream including the object of interest and the one or more graphical elements.

Abstract: Method for triggering changes to real-time special effects included in a live streaming video starts with a processor transmitting in real-time a video stream captured by a camera via a network. The processor causes a live streaming interface that includes the video stream to be displayed on the plurality of client devices. The processor receives a trigger to apply one of a plurality of special effects to the video stream and determines a first special effect of the plurality of special effects is associated with the trigger. The processor applies in real-time the first special effect to the video stream to generate a video stream having the first special effect and transmits in real-time the video stream having the first special effect via the network. The processor causes the live streaming interface that includes the video stream having the first special effect to be displayed on the plurality of client devices. Other embodiments are disclosed.
