  • Noise suppression filter
    Patent number: 10623738
    Abstract: A mechanism of video coding is provided. The mechanism includes generating a reconstructed image from an encoded video stream. The reconstructed image is filtered to create a filtered image. The filtering includes applying a noise suppression filter to the reconstructed image. The noise suppression filter may be applied immediately prior to applying a deblocking filter to the reconstructed image, between a deblocking filter and a sample adaptive offset (SAO) filter, between the SAO filter and an adaptive loop filter, or after the adaptive loop filter. The filtered image is then stored in a picture buffer in memory for use in encoding or for output to a display in decoding.

  • Noise suppression filter parameter estimation for video coding
    Patent number: 10595019
    Abstract: A mechanism of video coding is provided. The mechanism includes generating a reconstructed video frame. Noise suppression filter parameters are determined by partitioning the reconstructed video frame into blocks and matching the blocks to create patches. The noise suppression filter parameters are then determined based on the patches by creating a transformed matrix of patch frequencies. The noise suppression filter parameters include a noise estimation parameter that is a function of patch frequency. The noise suppression filter parameters are then employed to apply a noise suppression filter to the reconstructed video frame.
