Abstract: Example embodiments relate to techniques for volumetric performance capture with neural rendering. A technique may involve initially obtaining images that depict a subject from multiple viewpoints and under various lighting conditions using a light stage and depth data corresponding to the subject using infrared cameras. A neural network may extract features of the subject from the images based on the depth data and map the features into a texture space (e.g., the UV texture space). A neural renderer can be used to generate an output image depicting the subject from a target view such that illumination of the subject in the output image aligns with the target view. The neural render may resample the features of the subject from the texture space to an image space to generate the output image.

Abstract: Techniques are provided herein to form non-planar semiconductor devices in a stacked transistor configuration adjacent to stressor materials. In one example, an n-channel device and a p-channel device may both be gate-all-around transistors each having any number of nanoribbons extending in the same direction, where the n-channel device is located vertically above the p-channel device (or vice versa).

The stressor materials may include, for instance, a compressive stressor material adjacent to the p-channel device and/or a tensile stressor material adjacent to the n-channel device. The stressor material(s) may form or otherwise be part of a diffusion cut structure.
