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: Implementations include video image processing systems, methods, and apparatus for integrated video downscale in a video core. The downscaler computes and writes a display frame to an external memory. This frame may have the same resolution as a target display device (e.g., mobile device). The target display device then reads this display frame, rather than the original higher resolution frame. By enabling downscale during encoding/decoding, the device can conserve resources such as memory bandwidth, memory access, bus bandwidth, and power consumption associated with separately downscaling a frame of video data.

Abstract: Techniques are described for performing near visually lossless video recompression. The disclosed techniques generate video frames having relatively small bitrates and relatively small file sizes while retaining approximately a same level of visually perceivable video quality as the originally recorded video frames. In general, recompression of a video frame takes an input video frame and produces a second copy of the video frame that has the same or lower Nitrate. The proposed techniques address the problem of recompressing a video frame with no perceivable loss in visual quality (i.e., visually lossless recompression) compared to the original recording of the video frame. In addition, the disclosed techniques provide one-step recompression of video frames that includes a single decoding and encoding of each video frame.

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.
