Macro Block (MB) type judging algorithm is proposed based on MB′s space complexity. It reduces effectively the computational complexity of the video compression.
提出了基于宏块空间复杂度的宏块类型判断算法，有效地降低了视频压缩算法的计算复杂度。
A macro block using the same motion vector with the central macro block is regarded as a part of the face and is quantified with a smaller quantization parameter.
与中央宏块使用相同运动矢量的宏块被视为脸的部分，以较小的量化参数对其进行量化。
The efficient video coding technique finds out a motion vector of a central macro block, and detects whether the motion vector can be applied to other macro blocks in the video frame.
本发明高效视频编码法先找出中央宏块的运动矢量，并且检验该运动矢量是否可应用于视频帧中其它宏块。
