Three-dimensional nonseparable perfect reconstruction filter banks using three-dimensional nonseparable sampling by two, FCO, are proposed. Filter structures are derived and applied to digital video. Separation into two bands is obtained, and is shown to perform better from the perceptual point of view when compared to interlaced sequences resulting from the quincunx sampling of a progressively scanned signal in time-vertical dimensions.
