Abstract: An image segmentation system to perform operations that include causing display of an image within a graphical user interface of a client device, receive a set of user inputs that identify portions of a background and foreground of the image, identify a boundary of an object depicted within the image based on the set of user inputs, crop the object from the image based on the boundary, and generate a media item based on the cropped object, wherein properties of the media object, such as a size and a shape, are based on the boundary of the object.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program and a method for detecting a plurality of shots in a video, each shot comprising a sequence of frames; automatically generating a modification to a visual presentation of one or more objects in a first shot of the plurality of shots; and generating, for display, a plurality of representations each associated with a respective one of the plurality of shots. The program and method further include receiving a user selection of a given representation of the plurality of representations corresponding to the first shot; and in response to receiving the user selection of the given representation, generating, for display, an indication of the automatically generated modification to the visual presentation of the one or more objects in the first shot.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program and a method for receiving, by one or more processors, a video comprising one or more shots in a first aspect ratio; detecting a first shot of the one or more shots, the first shot comprising a sequence of frames; and identifying an object that appears throughout a continuous portion of frames of the sequence of frames in the first shot. A visual presentation of the object in the first shot is automatically modified and a modified video comprising the one or more shots in a second aspect ratio is generated based on the automatically modified visual presentation of the object in the first shot.

A visual presentation of the object in the first shot is automatically modified and a modified video comprising the one or more shots in a second aspect ratio is generated based on the automatically modified visual presentation of the object in the first shot.

Abstract: Inter-context coordination to facilitate synchronized presentation of image content is described. In example embodiments, an application includes multiple execution contexts that coordinate handling user interaction with a coordination policy established using an inter-context communication mechanism. The application produces first and second execution contexts that are responsible for user interaction with first and second image content, respectively. Generally, the second execution context provides a stipulation for the coordination policy to indicate which execution context is to handle a response to a given user input event. With an event routing policy, an event routing rule informs the first execution context if a user input event should be routed to the second execution context.
