....same redundancy as the LP: up to 33 when subsampling by two in each dimension. If the filters in the LP are orthogo nal partners (that is, h[n] g[ n] and g[n] is orthogonal to its translates with respect to the subsampling lattice) then LP is shown to be a tight frame with energy conservation [8]. In that case, assuming an image x is decomposed into J bandpass images hi, j = 1, 2, J and a lowpass image a j, then we have d Ilxll = IIO11 IlaJIl . 7) Now, in addition, we assume that the DFB is also orthogonal; it decomposes each bandpass image bj into directional coefficients dj ....
