Nvidia patents method to find noise in images by comparing pixel depths
Nvidia describes a way to clean up digital images by looking at how deep different pixels are. The system checks many pixels at once to see if their depth differences are too large, which helps it spot and remove unwanted visual noise.
In the filing’s own words
Apparatuses, systems, and methods are to cause an image denoising filter to identify noise within an image to be performed. In at least one embodiment, an image denoising filter identifies noise within an image noise based, at least in part, on whether a plurality of concurrent comparisons of pixel depths within the image exceed a threshold value.
What exactly they claim (claim 1)
1. One or more processors comprising: circuitry to perform an image denoising filter on an image by: performing, in parallel, a plurality of concurrent comparisons of pixel depths for pixels within overlapping tiles of the image; determining whether the plurality of concurrent comparisons of pixel depths within the image exceed a threshold value; and performing the denoising filter on the image based, at least in part, on the determination.
