Abstract: In various examples, processing pipelines for removing artifacts from images are described herein. Systems and methods are disclosed that use one or more multi-pass techniques to identify and process areas in an image that have artifacts. For instance, using a series of forward passes, the image is processed to generate multiple levels of images, where the levels of images are used to identify at least areas of the original image that include artifacts and areas of the original image that include true color edges. Next, using a series of backward passes, processing is performed on color values associated with the areas that include artifacts to determine new color values for the pixels within the areas. In some examples, dithering may then be performed on the new color values to distribute errors in quantization across the pixels and remove the artifacts.

Abstract: Apparatuses, systems, and techniques providing a teleportation system combining virtual reality and augment reality are provided. A first set of data associated with a real-world environment is received. An object in the real-world environment, and a first location of the object, are identified based on a subset of the first set of data. A second location of a first user within the real-world environment is identified based on the first set of data. A second set of data representing a first avatar of a guest user is received. A virtual representation of the real-world environment is generated based on the first and second sets of data, comprising the object positioned at the first location and at least one of a second avatar of the first user or the first avatar of the guest user. The virtual representation is send to a computing system associated with the guest user.

Abstract: A digital avatar system can process video streams and generate synthetic video with a digital avatar. The digital avatar provides the appearance of a participant from the video stream talking and one or more of performing various behaviors or actions consistent with the participant's behavior when they are live streamed. A digital avatar system can detect triggering events during a live stream and automatically switch to an avatar mode.
