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.
