  • Method and apparatus for three-dimensional wavelet transform
    Patent number: 6956903
    Abstract: Embodiments of a three-dimensional wavelet transform are described. An inverse three-dimensional discrete wavelet transformation (IDWT) is applied to a plurality of transformed video image sub-blocks. The sub-blocks of transformed video images are inverse transformed by applying a bit-based conditional decoding to the embedded zero tree encoded DWT coefficients of the block to obtain a DWT coefficient matrix, up-sampling respective sub-blocks of the DWT coefficient matrix by row, column and frame, filtering and combining one or more respective pairs of up-sampled sub-blocks to produce an up-sampled sub-block corresponding to each respective pair, reapplying the filtering and combining step to any produced up-sampled sub-block pairs until one up-sampled sub-block remains and multiplying the one remaining up-sampled sub-block by eight to produce a block at the next higher resolution.
