Abstract: Methods, systems, and media for selecting video formats for adaptive video streaming are provided. In some embodiments, the method comprises: receiving an indication of a video to be presented on a user device; identifying a group of quality metrics for each of a plurality of segments of the video, wherein each quality metric includes values for a particular segment and for a particular format of a group of available formats for the video; selecting a first format for a first segment of the video; causing the first segment of the video to be presented on the user device; identifying a quality of a network connection between the user device and a server that hosts the video; identifying a second format for a second segment of the video based on the quality of the network connection; determining whether a format of the video is to be changed from the first format to the second format based at least on the group of quality metrics for the second segment of the video; and, in response to determining that the format of the video is to be changed from the first format to the second format, causing the second segment having the second format to be presented by the user device.

Abstract: A method includes receiving, by a user device, a first bitstream. The first bitstream includes data corresponding to a media item. The first bitstream includes data for display at a first aspect ratio. The method further includes receiving a second bitstream including data corresponding to the media item for display at a second aspect ratio. The method further includes providing the first bitstream to a first bitstream decoder and the second bitstream to a second bitstream decoder. Operations of the first bitstream decoder and operations of the second bitstream decoder overlap in time. The method further includes determining whether to display the media item at the first or the second aspect ratio. The method further includes generating a composited media item based on the first bitstream and the second bitstream. The method further includes displaying the composited media item.

Abstract: Image denoising includes obtaining a saliency map for an image. The saliency map includes respective saliency scores for pixels of the image. Respective noise levels are assigned to the pixels using the respective saliency scores to obtain a noise level map. The image is denoised using the noise level map to obtain a denoised image. The denoised image is output, such as to a display or a storage device.

Abstract: A first aspect is a method for coding a group of pictures (GOP) that includes frames of a video. The method includes encoding, at least some of the frames of the GOP, using a first encoding pass to obtain encoding statistics; obtaining, using the encoding statistics, respective temporal dependency likelihoods (TDLs) for the at least some of the frames of the GOP, where the respective TDLs indicate contributions that the at least some of the frames make in reducing prediction errors of the GOP; obtaining a reference frame based on the respective TDLs; and using the reference frame in encoding at least some of the frames of the GOP in a second encoding pass.

Abstract: Encoding using media compression and processing for machine-learning-based quality metrics includes generating encoded frame data by encoding a current frame from an input video using a neural-network-based video quality model, which includes identifying optimal encoding parameters for encoding a current block, wherein the optimal encoding parameters minimize a rate-distortion optimization cost function, which includes using a gradient value for the current block obtained from a neural-network-based video quality model generated gradient map obtained from the neural-network-based video quality model for the current frame, obtaining a restoration filtered reconstructed frame by restoration filtering a reconstructed frame, obtained by decoding the encoded frame data, using the neural-network-based video quality model generated gradient map obtained for the reconstructed frame.

Abstract: A method is provided that may include receiving, at a server, an indication of a first video to be presented on a user device, determining, at the server based on video features of the first video, a group of predicted viewership scores for each format from a group of available formats for the first video, selecting, at the server, a first format for the first video based on the group of predicted viewership scores for the first video, causing the first video to be presented on the user device, identifying a quality of a network connection between the user device and the server that hosts the first video during the presentation of the first video on the user device, receiving an indication of a second video to be presented on the user device, identifying a change in the quality of the network connection between the user device and the server, determining whether a format of the second video is to be changed from the first format to a second format based at least in part on the change in the quality of the network connection between the user device and the server, and in response to determining that the format of the second video is not to be changed from the first format to the second format, causing the second video to be presented by the user device.
