motion compensated prediction meaning in Chinese
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。
