Abstract: Multiple successively spatially downsampled versions of a rendered image frame are generated for at least one two-dimensional signal component of one or more two-dimensional signal components of an image frame, and one or more versions of the rendered image frame are selected from among the rendered image frame and the spatially downsampled versions of the rendered image frame for sampling a texture feature based, at least in part, on a prediction computed by a neural network.

Abstract: Disclosed are process and devices for processing an image frame. An image frame rendered on rendering instances may comprise pixel values for one or more lighting components. One or more first buffers may store accumulations of pixel values for the one or more lighting components over at least some past rendering instances. One or more second buffers may store pixel values for the one or more lighting components of a processed image frame. Pixel values in the one or more first buffers may be combined with pixel values in the one or more second buffers to provide pixel values for the one or more lighting components in an accumulated image frame.

Abstract: Example methods, apparatuses, and/or articles of manufacture are disclosed that may be implemented, in whole or in part, in techniques to process image signal intensity values sampled from a multi color channel imaging device. In particular, such techniques may comprise application of convolution operations with kernel coefficients selected from a set of coefficient values such that the same coefficient value is to be applied to image signal intensity values of multiple pixel locations in an image frame.

Abstract: One or more lighting components are projected onto pixel locations of a rendered image with sampling locations set off from pixel location centers according to associated jitter vectors. The sampled image is denoised in way that preserves the associated jitter vectors, and may be performed separately for different lighting components. The denoised image is processed using upsampling and/or temporal antialiasing, using the associated jitter vectors, to an image format having a spatial resolution at least as high as the denoised image.

Abstract: A first image frame in a first resolution format comprising image signal intensity values mapped to first pixel locations has sampling points offset from the centers of first pixel locations according to associated jitter vectors. The image signal intensity values are mapped to second pixel locations in a second image frame in a second resolution format based at least in part on the jitter vectors, the second resolution format being higher resolution than the first resolution format. The mapped image signal intensity values are combined with image signal intensity values of an accumulated history image buffer according to coefficients predicted by a neural network such as based on magnitudes of the jitter vectors. Interpolated pixel image intensities are added to the accumulated history buffer for empty or null pixel locations in the second image frame in the second image format. Upsampling artifacts such as checkerboarding and aliasing are reduced.

Abstract: Disclosed are devices and/or processes to process image frames expressed in part by different lighting components, such as lighting components generated using ray tracing. In an embodiment, different lighting components of a previous image frame may be separately warped and combined with like lighting components in a current image frame.

Abstract: Example methods, apparatuses, and/or articles of manufacture are disclosed that may implement, in whole or in part, techniques to process portions of an image frame according to a level of diminished signal information. Portions of an image frame experiencing diminished signal information may be sampled a lower rate/more sparsely to reduce impacts to downstream image processing resources.
