Nvidia patents method to sharpen images using neural networks
Nvidia describes a technique that uses neural networks to create higher-resolution images from lower-resolution inputs. The system calculates specific blending weights based on sub-pixel offsets to mix current and previous image data, resulting in a clearer final picture.
In the filing’s own words
Apparatuses, systems, and techniques are presented to generate images. In at least one embodiment, one or more neural networks are used to generate one or more images using one or more pixel weights determined based, at least in part, on one or more sub-pixel offset values.
What exactly they claim (claim 1)
1. One or more processors, comprising: circuitry to use one or more neural networks to; determine a first blending weight and a second blending weight based, at least in part, on one or more upsampled images generated using one or more sub-pixel offsets associated with one or more low resolution images; perform, using the first blending weight, a first blending of pixel values of the one or more upsampled images with pixel values of one or more prior upsampled images to generate one or more intermediate image representations; perform, using the second blending weight, a second blending of the pixel values of the one or more upsampled images with pixel values of the one or more intermediate image representations; and generate one or more output images.
