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.

Abstract: Various innovations facilitate the use of intra-picture prediction modes such as palette prediction mode, intra block copy mode, intra line copy mode and intra string copy mode by an encoder or decoder when wavefront parallel processing (“WPP”) is enabled. For example, for a palette coding/decoding mode, an encoder or decoder predicts a palette for an initial unit in a current WPP row of a picture using previous palette data from a previous unit in a previous WPP row of the picture. Or, as another example, for an intra copy mode (e.g., intra block copy mode, intra string copy mode, intra line copy mode), an encoder enforces one or more constraints attributable to the WPP, or a decoder receives and decodes encoded data that satisfies one or more constraints attributable to WPP.

Abstract: Techniques are described for efficiently encoding video data by skipping evaluation of certain encoding modes based on various evaluation criteria. In some solutions, intra-block evaluation is performed in a specific order during encoding, and depending on encoding cost calculations of potential intra-block encoding modes, evaluation of some of the potential modes can be skipped. In some solutions, some encoding modes can be skipped depending on whether blocks are simple (e.g., simple vertical, simple horizontal, or both) or non-simple. In some solutions, various criteria are applied to determine whether chroma-from-luma mode evaluation can be skipped. The various solutions can be used independently and/or in combination.

Abstract: Innovations in the use of base color index map (“BCIM”) mode during encoding and/or decoding simplify implementation by reducing the number of modifications made to support BCIM mode and/or improve coding efficiency of BCIM mode.

Other innovations relate to mapping of index values in BCIM mode or prediction of elements of an index map in BCIM mode. Still other innovations relate to handling of exception values in BCIM mode.

Abstract: Disclosed is a method for estimating ultrasound attenuation coefficient by use of aberration compensation and the reference phantom method. Measurements on a human sample at a single transmit frequency and on multiple reference phantoms at a plurality of transmit frequencies are performed respectively. The center frequencies of the echo signals at the depth of the top edge of the region of interest are calculated. A specific reference phantom at a specific transmit frequency is selected by the echo signals whose center frequencies are closest to the center frequencies of the echo signals from the human sample at the aforementioned depth to compensate for the aberration. Then the spectra of the echo signals from the selected reference phantom at the selected transmit frequency and the spectra from the echo signals from the human sample are used to estimate the attenuation coefficient of the human sample by following the reference phantom method.
