Abstract:
1. A method comprising: encoding a video region using first parameters, the encoding using first parameters including applying adaptive Wiener filtering to the video region using the first parameters; encoding the video region using second parameters, the encoding using second parameters including applying adaptive Wiener filtering to the video region using the second parameters; setting a lowest rate-distortion cost of the video region as the lowest among: a rate-distortion cost resulting from adaptive Wiener filtering of the video region using the first parameters, a rate-distortion cost resulting from adaptive Wiener filtering of the video region using the second parameters, and a rate-distortion cost resulting from not applying adaptive Wiener filtering to the video region; selecting parameters from among the first and second parameters associated with a lowest rate-distortion cost in response to the lowest rate-distortion cost resulting from adaptive Wiener filtering of the video region using the first or the second parameters; selectively transferring selected parameters for the video region in response to the lowest-rate distortion cost resulting from adaptive Wiener filtering using first or second parameters, wherein transferred selected parameters are for use to modify and replace at least one pixel; and selectively transferring no filter parameters associated with the video region in response to the lowest rate-distortion cost resulting from not applying adaptive Wiener filtering to the video region.
