Abstract: The technology disclosed herein involves using a transformation curve to modify colors of images so that those images are more easily viewed by persons with a color vision deficiency (CVD). The transformation curve is applied to spectral versions of images in which each pixel has a spectral representation to modify the spectral versions of the images. A spectral version of an image is modified by, for each pixel of the spectral version of the image, modifying intensities of one or more wavelengths by applying the one or more wavelengths to the transformation curve, which transforms the intensities from source wavelengths to destination wavelengths. The modified spectral version of the image is then modified to a modified version of the image in a color space, such as the RGB color space.

Abstract: One embodiment of a method for rendering one or more graphics images includes tracing one or more rays through a graphics scene; computing one or more surface normals associated with intersections of the one or more rays with one or more surfaces, where computing each surface normal includes: computing a plurality of intermediate surface normals associated with a plurality of adjacent voxels of a grid, and interpolating the plurality of intermediate surface normals; and rendering one or more graphics images based on the one or more surface normals.

Abstract: Block compression schemes used for image compression are susceptible to generating image blocks having redundant bit sets (i.e. a redundant bit combination), where one of the bit sets in the block is not meaningfully different from the other bit set in the block. As a result, one of the bit sets will be meaningless to a decompression scheme used to decompress the image and thus will not contribute to improving a quality of the decompressed image. The present disclosure provides a technique to exploit redundant bit combinations in a compressed representation of an image, including to exploit more than just the simple case of bit sets that are identical. Exploiting a redundant bit combination will allow an otherwise meaningless bit set to be used for some other discriminating purpose, which can allow for a higher image quality after decompression.

Abstract: Techniques are disclosed herein for interleaving textures. In the disclosed techniques, multiple textures that would otherwise be accessed separately are interleaved into a single, interleaved texture that can be used to access the multiple textures together. The interleaved texture can include alternating blocks from the multiple textures. The interleaved texture can be generated when the multiple textures are being loaded into memory. Further, the interleaved texture can be accessed using multiple texture headers that are associated with different textures in the interleaved texture. Each of texture headers includes a stride indicating the distance between two blocks from a same texture in the interleaved texture.

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 texture level of detail (LOD) approximation may be performed utilizing ray differentials and a G-buffer. For example, a scene to be rendered is identified, and a G-buffer of the scene is rendered. Additionally, ray tracing is started for the scene, and during the ray tracing, a ray differential is created by accessing the G-buffer. Further, the created ray differential is appended to a current ray, and the created ray differential is traced.
