Abstract: Systems, methods, and computer-readable media are provided for efficient control and data utilization between processing components of a system. An method can include obtaining image data captured by an image sensor; prior to a first computing component performing a first set of operations on the image data and a second computing component performing a second set of operations on the image data, determining one or more common operations included in the first set of operations and the second set of operations, wherein the first set of operations is different than the second set of operations; performing the one or more common operations on the image data; and generating an output of the one or more operations for use by the first computing component to perform the first set of operations and the second computing component to perform the second set of operations.

Abstract: Systems, methods, and computer-readable media are provided for efficient video coding. An method can include determining, during a first coding stage implemented at a first frame rate, first motion vectors for a first subset of frames in a sequence of frames; determining, during a second coding stage, second motion vectors for a second subset of frames in the sequence of frames, wherein a portion of the second motion vectors is calculated based on one or more of the first motion vectors; and reconstruct, during the second coding stage, the first subset of frames using the first motion vectors; and reconstruct, during the second video coding stage, the second subset of frames using the second motion vectors, the first coding stage and the second coding stage being implemented in parallel, and the second coding stage being implemented at a second frame rate that is higher than the first frame rate.

Abstract: Systems and techniques are described for data encoding using a machine learning approach to generate a distortion prediction {circumflex over (D)} and a predicted bit rate {circumflex over (R)}, and to use {circumflex over (D)} and {circumflex over (R)} to perform rate-distortion optimization (RDO). For example, a video encoder can generate the distortion prediction {circumflex over (D)} and the bit rate residual prediction based on outputs of the one or more neural networks in response to the one or more neural networks receiving a residual portion of a block of a video frame as input. The video encoder can determine bit rate metadata prediction based on metadata associated with a mode of compression, and determine {circumflex over (R)} to be the sum of and . The video encoder can determine a rate-distortion cost prediction Ĵ as a function of {circumflex over (D)} and {circumflex over (R)}, and can determine a prediction mode for compressing the block based on Ĵ.
