motion compensated prediction meaning in English
采用了运动补偿预测
Examples
- Loss of information during transmission of compressed video over error prone networks may lead to objectionable visual distortion in the decoded video , and such distortion can propagate to many frames because of the motion compensated prediction and the variable - length coding used
采用运动补偿预测及可变长编码的压缩视频数据，在极易发生干扰的网络环境中传输时，信道传输差错对压缩编码图像质量影响很大，有时甚至会导致整个视频通信完全失效。 - Motion compensated prediction error image has significant amplitudes mainly along the boundaries of moving objects , correspondingly its wavelet coefficients contain large energy in high frequency bands . this greatly reduces the coding efficiency of ezw . it is first provided that the correspondence between the significant amplitudes area of the mcp error image and the wavelet coefficient significant map , then encode the significant map efficiently using quadtree approach , followed by bit - plane coding the significant coefficients to produce an embedded data stream . experiment result shows that compared to ezw and zte , the proposed algorithm is more efficient and has better performance
算法对于运动补偿余量误差帧首先进行小波变换，并选取适当的阈值，用重要图表示大于该阈值的重要系数。根据残差帧小波系数的统计特性，用四叉树方法编码重要图，并对重要系数作位面编码，生成嵌入式码流。实验表明，与ezw ， zte等算法相比较，该算法编码效率高，复现图像质量好。
