Abstract: In various examples, properties may be determined for image regions, where the image regions are indicated by output data generated using MLMs. An encoder may use the properties to generate encoded images using encoding quality settings for the image regions. When an encoded image is decoded and applied to the MLMs, corresponding output data may indicate an image region which is likely to correspond to an encoded image region of the encoded image, and which may be applied to at least one MLM. Thus, the properties for encoding an image region to an encoded image can be adapted to control the visual quality of an image region determined from a decoded version of the encoded image. The properties may be determined based at least on performance metric values for the MLMs or based at least on a ranking of the image regions.

Abstract: Systems and methods are described for processing video content. Content may be encoded/transcoded for delivery to a computing device that requested the content. The content may be encoded as temporally interlaced blocks, which interlaces frames over time. Because the frames are temporally interlaced, the computing device may be able to decode and play back a full-length or complete video at a reduced quality even if every temporally interlaced block was not received by the computing device, such as when network bandwidth is low or the network connection is disrupted. Receiving only a portion of the temporally interlaced blocks may be still be sufficient to display a full-length video at a reduced quality (e.g., at a reduced bit rate).

Abstract: Low complexity, hardware-friendly techniques are proposed for video coding systems to mitigate banding artifacts while maintaining the compression efficiency. In general, the proposed techniques consist of two stages including a banding detection stage and a de-banding stage. The banding detection stage may identify the image/video regions where the banding artifact may be present based on gradient information and other information. The de-banding stage may apply corrective techniques to regions identified as likely to possess banding artifacts. In one embodiment, the de-banding adapts the filtering logic proposed by prior video coding standards for other filtering applications to mitigate banding. When implemented over the AV1 video coding standard and the AOM Video Model (AVM) reference software, the proposed technique improves subjective quality significantly at a reasonable hardware implementation cost.
