Patent ID: 7801220

Claim:
A method comprising: creating a balanced interpolation reference for motion estimation during in-band wavelet video coding, the creating comprising: using leaky prediction based on spatial lowpass band information and overcomplete lowpass band information; deriving a first interpolation reference frame for the motion estimation, wherein the first interpolation reference frame is derived from spatial lowpass band (LL) information; deriving a second interpolation reference frame for the motion estimation, wherein the second interpolation reference frame is derived from overcomplete lowpass band (LL) information that includes some spatial highpass band information; and attenuating a difference between the first interpolation reference frame and the second interpolation reference frame using lifting with a leaky prediction factor in order to obtain an attenuated interpolated reference frame; and summing the attenuated interpolation reference frame and the first interpolation reference frame to obtain the balanced interpolation reference for the motion estimation; and performing the motion estimation using the balanced interpolation reference.
