Abstract
A technique to perform edge-aware spatial noise filtering that may filter random noise from frames while maintaining the edges in the frames. The technique may include receiving a frame comprising a pint ht of pixels, filtering a subset of the plurality of pixels based on a weighting factor associated with each pixel of the subset of pixels, wherein the weighting factor is at least in part based on a difference in pixel value between the pixel and the individual pixels in the subset, and providing the filtered pixel to an encoder for encoding. Example implementation may include a spatial noise filter to receive an image, the noise level, and configuration parameters, and configured to determine weighting factors of pixels of the image based on differences in pixel values and a set of configuration parameters, and further configured to filter noise from the image based on the weighting factors of the pixels.
