    碼變換器速率適配單元
  3. A decoding algorithm based on transform and fast hadamard transform changes the matrix multiplication to the addition, subtraction and position exchanging among the matrix elements, so reduces the demand of the instrument for computer

    基於變換和快速阿達瑪變換的解碼演算法，將矩陣乘法簡化為矩陣元素間的加、減運算和位置交換，降低了儀器對微機系統的要求。
  4. This method can maintain the superiority of traditional wavelet transform to effectively remove temporal redundancy. in addition, owing to the feather of the integer form of wavelet lifting scheme, the computational complexity and memory requirement are reduced, which can enhance the performance of the wavelet video coding system

  5. In this paper, two important modifications in dct - based coding algorithm are suggested after making deep study on the generally used scheme of h. 263 coder. first, we find plenty of invalid computation in the transformation part of the h. 263 coder and an improved scheme based on the pre - transform decision to avoid invalid computation is proposed. second, in the motion estimation part of the coder, we find that normal search algorithms are not effective, which neglects different levels of motion in image sequences, and we suggest a new search algorithm which has variable search region based on the difference of motion level. combining the pre - transform decision scheme with variable search region method in motion estimation, a global decision coding scheme is provided, which greatly increases the coding speed of h. 263 coder

    本文對h . 263編碼演算法的現有實現方法作了深入的分析，首先發現變換部分存在大量無效運算，提出了在變換前加判決的前變換判決的編碼方案，以壓縮無效的變換運算；其次發現運動估計部分由於忽略了圖像場景的分級運動而存在一定的無效搜索運算，提出了基於分級運動的可變搜索域法來壓縮無效的搜索運算；最後將前變換判決方案與運動估計的可變搜索域法有機地結合在一起，提出了全局判決編碼方案，從而比較全面地改進了現有實現方法，因而能大幅度地提高編碼器的編碼速度
