Device-consistent techniques for predicting absolute perceptual video quality
In various embodiments, a perceptual quality application determines an absolute quality score for encoded video content viewed on a target viewing device. In operation, the perceptual quality application determines a baseline absolute quality score for the encoded video content viewed on a baseline viewing device. Subsequently, the perceptual quality application determines that a target value for a type of the target viewing device does not match a base value for the type of the baseline viewing device. The perceptual quality application computes an absolute quality score for the encoded video content viewed on the target viewing device based on the baseline absolute quality score and the target value. Because the absolute quality score is independent of the viewing device, the absolute quality score accurately reflects the perceived quality of a wide range of encoded video content when decoded and viewed on a viewing device. |

Method and apparatus for omnidirectional video coding with adaptive intra most probable modes
In omnidirectional videos, only some intra prediction directions may be relevant for intra prediction.

To improve compression efficiency, we propose to reduce the number of possible directions, based on the location of the block to be encoded or decoded in the frame. In various embodiments, we may adapt the derivation of the MPM in order to take into account the reduction of intra directions depending on geometric distortions. The encoding method can also be adapted to reduce the number of modes to estimate for a block in omnidirectional videos. The coding of the syntax elements representing the intra direction can also be improved. |

2D-to-3D video frame conversion
A wide spread adoption of 3D videos and technologies is hindered by the lack of high-quality 3D content. One promising solution to address this problem is to use automated 2D-to-3D conversion. However, current conversion methods, while general, produce low-quality results with artefacts that are not acceptable to many viewers. Creating a database of 3D stereoscopic videos with accurate depth is, however, very difficult. Computer generated content can be used to generate high-quality 3D video reference database for 2D-to-3D conversion. The method transfers depth information from frames in the 3D reference database to the target frame while respecting object boundaries. It computes depth maps from the depth gradients, and outputs a stereoscopic video. |

For each kernel position, the convolving is performed, for each equal-valued kernel region, by calculating the difference between the cumulative sum of the pixel corresponding to the last element in the equal-valued kernel region and the cumulative sum of the pixel corresponding to the element immediately preceding the first element in the region, and summing the differences for all equal-valued kernel regions. The differences sum is scaled to provide a processed target pixel value. |

Adaptive demodulation reference signals in wireless communication systems
The described technology is generally directed towards adapting the demodulation reference signal sent in a wireless resource data block based on channel estimation performance. In general, if the demodulation reference signal received was not successfully able to be used to demodulate the resource data block, the demodulation reference signal density can be increased up to a maximum density, which costs resource elements but improves the channel estimation accuracy. If the demodulation reference signal received was able to be used to demodulate the resource data block, the demodulation reference signal density can be decreased down to minimum density, which saves resource elements for data. The network device can use HARQ ACK/NACK data (e.g., a current count or counted over a time period) to determine channel estimation performance, and/or the user equipment can recommend a demodulation reference signal density change. |

For example, a baseband unit can compute a precoder matrix from an estimated channel associated with an uplink signal. Once the baseband unit computes the channel, it can determine the coefficients for the linear combination of the basis vectors, which are known at the baseband unit and the radio unit as well. The baseband unit can estimate the path loss and the signal interference to noise ratio and determine the basis vectors. The baseband unit can then compress the coefficients and transmit the coefficients to the radio unit. When the radio unit receives the compressed coefficients, the radio unit can reconstruct the precoder matrix and apply to reference signals and data traffic channels. |

Hybrid transmission wiring verification
In an electrified vehicle having a synchronous traction motor, an inverter is connected to stator windings by three power cables. If these cables are accidentally connected to the wrong windings, the resulting torque will not match the desired torque, and may even be in the wrong direction. To avoid this problem, a test is performed any time that the cables may have been unplugged and re-connected. The inverter is commanded to generate a rotating magnetic field while the rotor is held stationary, resulting in a positive and a negative response current. A relationship between a phase angle of the negative response current and the rotor position indicates which cables are connected to which windings. If the cables are incorrectly connected, the controller disables the motor and informs an operator which cables to swap to achieve correct connection. |
