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.

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.

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.
