    摘要: Embodiments of a color video coding and decoding scheme are disclosed. In one embodiment, an efficient color coding scheme for color video using three dimensional (3-D) discrete wavelet transforms (DWT) employing correlation among different color components is described. At least one of the color components is coded, and an adjustment to at least some of the remaining color components relative to the coded color component are then coded. This adjustment comprises a partial error adjustment based at least in part on a ratio of color components intensities. Other embodiments, for instance for decoding, are described and claimed.

    摘要: 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.
