PIXEL INTERPOLATION METHOD AND SYSTEM

摘要

A method of computing a frame to be predicted from a first and a second reference frames, said method comprising for each pixel to be predicted in the frame to be predicted the acts of defining a first and a second pixel corresponding, respectively in said first and second reference frames, to the pixel to be predicted along the motion vector of said pixel to be predicted; computing a first predicted pixel as a combination of pixels in a neighborhood of said first pixel using first combination coefficients, said first combination coefficients allowing computing said second pixel as a combination of pixels of said neighborhood of said first pixel, wherein said first combination coefficients are calculated using a similarity function representing a grey level difference between a pixel of said neighborhood of said first pixel and the pixel to be predicted; and computing said pixel to be predicted from said first predicted pixel.
