    Abstract: Disclosed are systems, methods, devices and computer-readable media for image fetching for timeline scrubbing of digital media. In some implementations, a method comprises: receiving at a first time prior to receiving a scrub command, a first set of scrub images associated with digital media, the first set of scrub images having a first set of positions on a timeline of the digital media; receiving a first scrub command; receiving at a second time after the first time, a second set of scrub images associated with the digital media, the second set of scrub images having a second set of positions on the timeline that fill time gaps in the first set of positions on the timeline; animating, a timeline overlay including the timeline, a playhead and a scrub image window; and selecting a scrub image from the first or second sets of scrub images for presentation in the scrub image window.

    Abstract: A video playback buffer adjustment system is disclosed. The video playback buffer has a target size, measured in units of time of content, and includes a compressed frames queue and an uncompressed frames queue. The uncompressed frames queue has a minimum threshold queue size. If the size of the uncompressed frames queue falls below the minimum threshold size, then a next encoded frame in the compressed frames queue is removed from the compressed frames queue, decoded, and enqueued in the uncompressed frames queue. If a current size of the playback queue exceeds the target size plus Δ (a hysteresis value), then a playback frame rate is increased, and a presentation time of one or more frames in the uncompressed frames queue is adjusted according to the increased playback frame rate. If the playback queue size is less than the target size minus Δ, the playback speed can be reduced.

    Abstract: Techniques disclosed herein permit a party to identify a first (low-resolution) image as it is displayed on their, for example, smart phone during a video conference call. Identifying information specific to the first image may be collected and a request for a high-resolution copy of the image sent to the party sourcing the transmitted image. The high-resolution image may be sent from the image's sourcing device to the requestor's device during, or after, the video conference call. In some embodiments, the high-resolution image may be sent through an alternate communication channel (e.g., via a chat, social media or email channel). In other embodiments, the high-resolution image may be sent to a network-based service from which the requestor may obtain the image. In one embodiment, the sourcing device may message the requesting device that the image has been sent to the network-based service.

    Abstract: The present disclosure describes systems and techniques relating to generating three dimensional (3D) models from range sensor data. According to an aspect, frames of range scan data captured using one or more three dimensional (3D) sensors are obtained, where the frames correspond to different views of an object or scene; point clouds for the frames are registered with each other by maximizing coherence of projected occluding boundaries of the object or scene within the frames using an optimization algorithm with a cost function that computes pairwise or global contour correspondences; and the registered point clouds are provided for use in 3D modeling of the object or scene. Further, the cost function, which maximizing contour coherence, can be used with more than two point clouds for more than two frames at a time in a global optimization framework.
