Nvidia patents video coding that cleans up noise before encoding
Nvidia describes a video encoder that uses a 'lookahead' step to preview frames before final processing. It applies a temporal filter during this preview to remove noise, which helps the system choose better ways to compress the video data.
In the filing’s own words
Systems and methods herein are for a video encoder to be associated with a temporal filter and a coding tree and that can perform a main pass for video encoding using individual video blocks towards prediction of at least one frame associated with the media stream, where the coding tree is associated with a lookahead pass, and where the temporal filter can enable denoising within the lookahead pass to reduce an effect of noise in one or more of motion estimation or mode selection of the video encoding.
What exactly they claim (claim 1)
1. A video encoder to be associated with a temporal filter and a coding tree and to perform a main pass and a lookahead pass for video encoding of a media stream, wherein the temporal filter is to enable denoising within the lookahead pass.
