Abstract: In one embodiment, a method includes capturing images of a first user wearing a VR display device in a real-world environment. The method includes receiving a VR rendering of a VR environment. The VR rendering is from the perspective of the mobile computing device with respect to the VR display device. The method includes generating a first MR rendering of the first user in the VR environment. The first MR rendering of the first user is based on a compositing of the images of the first user and the VR rendering. The method includes receiving an indication of a user interaction with one or more elements of the VR environment in the first MR rendering. The method includes generating, in real-time responsive to the indication of the user interaction with the one or more elements, a second MR rendering of the first user in the VR environment. The one or more elements are modified according to the interaction.

Abstract: The application describes method of modifying an image. The method may include a step of receiving, via an user interface of a service, a reference image and an input including text associated with the reference image. The method may also include a step of determining, via a trained machine learning (ML) model, one or more features of the reference image. The method may further include a step of modifying, via one or more trained latent diffusion models (LDMs), the reference image based upon the determined features and the received input. Any one or more of a background of the reference image, an area of the reference image or a style of the reference image may be modified. The method may even further include a step of causing to display, via the user interface of the service, the modified image.

Abstract: A method includes generating first and second series of segmentation masks for a first and second series of images in a video, respectively. The first series of segmentation masks are generated by using a machine-learning model to (1) generate a first segmentation mask based on a first image in the first series of images and a predetermined fixed segmentation mask, and (2) generate a second segmentation mask based on a second image in the first series of images and the first segmentation mask. The second series of segmentation masks are generated by using the machine-learning model to (1) generate a third segmentation mask based on a third image in the second series of images and the predetermined fixed segmentation mask, and (2) generate a fourth segmentation mask based on a fourth image in the second series of images and the third segmentation mask.

Abstract: In one embodiment, a method includes using one or more cameras of a mobile computing device to capture one or more images of a first user wearing a VR display device in a real-world environment. The mobile computing device transmits a pose of the mobile computing device with respect to the VR display device to a VR system. The mobile computing device receives from the VR system a VR rendering of a VR environment. The VR rendering is from the perspective of the mobile computing device with respect to the VR display device. The method includes segmenting the first user from the one or more images and generating, in real-time responsive to capturing the one or more images, a MR rendering of the first user in the VR environment. The MR rendering of the first user is based on a compositing of the segmented one or more images of the first user and the VR rendering.
