Abstract: Image augmentation effects are provided on a device that includes a display and a camera. A first stream of image frames captured by the camera is received and an augmented reality effect is applied thereto to generate an augmented stream of image frames. The augmented stream of image frames is displayed on the display in real time. A second stream of image frames, corresponding to the first stream of image frames, is concurrently saved to an initial video file. The second stream of image frames can later be retrieved from the initial video file and the augmented reality effects applied thereto independently of the first stream of image frames.

Abstract: Examples relate to systems and methods for generating videos with precise camera control using a camera-conditioned video diffusion transformer (DiT) model. The model performs a denoising process through a series of pretrained video DiT blocks, where camera trajectory information is processed through a camera conditioning branch to generate camera activations. During an initial portion of denoising passes, the process is conditioned on camera activations for an initial subset of video DiT blocks, while later denoising passes proceed without camera conditioning. This approach leverages the insight that camera motion is established early in the denoising process, enabling precise camera control while maintaining high visual quality.

Abstract: A mobile device uses information from another mobile device to perform satellite position fix operations. The information enables the mobile device to perform the satellite position fix operation with less power. Additionally, the information enables the mobile device to determine a position of the mobile device more precisely at significantly lower power consumption. Example methods include receiving, via a wireless communication protocol, an indication of a space vehicle identification (SVID) and an indication of a frequency error for a space vehicle indicated by the SVID and performing an acquisition procedure for the space vehicle using the frequency error as a starting frequency. The method may further include receiving a ratio of the carrier power over the noise power for a unit bandwidth (C/N), determining an integration time based on the C/N, and performing the acquisition procedure for the space vehicle using the frequency errors as a starting frequency error and using the integration time.
