Abstract: Approaches to robust encoding and decoding of escape-coded pixels in a palette mode are described. For example, sample values of escape-coded pixels in palette mode are encoded/decoded using a binarization process that depends on a constant value of quantization parameter (“QP”) for the sample values. Or, as another example, sample values of escape-coded pixels in palette mode are encoded/decoded using a binarization process that depends on sample depth for the sample values. Or, as still another example, sample values of escape-coded pixels in palette mode are encoded/decoding using a binarization process that depends on some other fixed rule. In example implementations, these approaches avoid dependencies on unit-level QP values when parsing the sample values of escape-coded pixels, which can make encoding/decoding more robust to data loss.

Abstract: Innovations in intra block copy (“BC”) prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding and decoding. For example, some of the innovations provide ways to select block vector (“BV”) values more effectively. Other innovations provide ways to encode/decode BV values more efficiently. Still other innovations address how to perform in-loop deblock filtering when a block has intra BC prediction mode, or address how to perform intra BC prediction when constrained intra prediction is enabled.

Abstract: Innovations in encoder-side options for intra block copy (“BC”) prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding. For example, some of the innovations relate to concurrently performing block vector (“BV”) estimation and making block splitting decisions for a block. Other innovations relate to selectively merging blocks into a larger block during BV estimation.

Abstract: In various examples, systems and methods are disclosed that perform motion detection across image frames, such as optical flow determination, to synchronize an asynchronous frame with respect to a target time for the asynchronous frame. For example, image frames from a sensor can be processed by an optical flow accelerator to detect displacement across the image frames, and the displacement can be used to interpolate a modified frame at the target time. This can be used to perform data collection and combining operations such as stitching and/or reconstruction. The synchronization can be performed from sensor data from sensors such as cameras, LIDAR sensors, and/or RADAR sensors.
