AI Technical Summary

Technical Problem

Traditional spatial upscalers require high-quality anti-aliased source images and often produce low-quality upscaled output, especially when the source resolution is low, leading to artifacts such as shimmering and poor edge reconstruction.

Method used

Implementing a super-resolution upscaler that uses temporal feedback to reconstruct high-resolution images by processing low-resolution frames, maintaining or improving image quality through techniques like auto-exposure, reprojection accumulation, and sharpening.

Benefits of technology

Enhances image quality and reduces artifacts by leveraging temporal feedback to upscale low-resolution frames to high-resolution, making costly rendering operations like hardware ray tracing more practical.

Abstract

A first frame of the video stream is obtained, the first frame being defined by a plurality of pixels associated with a set of color data, and a determination is made that a pixel of the plurality of pixels includes high frequency information, and in response to determining that the pixel includes high frequency information, a pixel lock is generated for the pixel such that color data associated with the pixel is maintained during a color accumulation process for at least one of the first frame or a second frame of the video stream subsequent to the first frame.
