Abstract:
1. A method of filtering pixels of video frames of a sequence of video frames for facilitating video encoding thereof, said method comprising: prior to MPEG compression encoding of the video frames, obtaining pixel values of the video frames of the sequence of video frames; programmably vertically filtering noise from said pixel values of said video frames prior to said MPEG compression encoding, said programmably vertically filtering comprising obtaining vertical filter coefficients for use in vertically filtering said pixel values, wherein said vertical filter coefficients comprise at least two programmable luminance filter coefficients and at least two programmable chrominance filter coefficients, and wherein the programmably vertically filtering further comprises: further comprising performing at least one of said vertically filtering luminance components of said pixel values and said vertically filtering chrominance components of said pixel values, as follows: vertically filtering luminance components of said pixel values by determining filtered luminance component data using: where: Lum(filtered)=a filtered pixel luminance component, L Pl vertically filtering chrominance components of said pixel values by determining filtered chrominance component data using: where: Chr(filtered)=a filtered pixel chrominance component, C Pc
