  • Adaptive Pixel Sampling Order for Temporally Dense Rendering
    Publication number: 20230269391
    Abstract: A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern.
    Type: Application

  • Reconstruction for temporally dense ray trace rendering
    Patent number: 11120609
    Abstract: A method dynamically selects one of a first sampling order and a second sampling order for a ray trace of pixels in a tile where the selection is based on a motion vector for the tile. The sampling order may be a bowtie pattern or an hourglass pattern. Subframes generated based on the sampling order are communicated over a bus along with motion vectors for tiles of the subframes.

  • Spatio-temporal image metric for rendered animations
    Patent number: 10810455
    Abstract: An image processing method transforms image sequences into luminances, filters the luminances, determines the temporal differences between the luminances, performs a frequency domain transformation on the temporal differences, and applies a temporal contrast sensitivity function envelope integral to the frequency transform output to generate a temporal image metric. The temporal image metric may be applied for example to train a neural network or to configure a display device to depict a visual indication of the temporal image metric.

  • Universal codec
    Patent number: 10186236
    Abstract: Techniques related to coding data including techniques for coding data using a universal codec are generally described. In some examples, such techniques may provide a universal (or unified) codec parameterized using a small set of parameters, which may be used to adapt the codec to different types of data to be compressed.
