针对帧内预测宏块，提出了“参考块缩放法”，在不明显增加解码复杂度的情况下，有效减少误差漂移。

And the method of reference block scaling was proposed for inter coded macroblocks, which can reduce error drift effectively without increasing decoding complexity.

此外，由于用偏心权距离的方法来寻找邻域，所以无论是在方向方面，还是在缩放尺度方面，这一方法都会得到较好的效果。

Furthermore, we can get a well performance on both orientation and scale adaptive side, because we utilize the CAM weighted distance to search the neighborhood of a data point.

图片缩放的处理方法有很多种，常规的有抽点法、平均法、双线性法。

There are many methods of scaling pictures, the common of which are snapshot method, average method and bilinear method.
