可变块分割的方法是采用基于多分辨率四叉树分解的运动分割。
The variable block segmentation is based on a multi-resolution quadtree-based motion segmentation.
可变块大小的一个重要使用是压缩(因为压缩时的结果块大小理想情况下将小于初始大小)。
One important use of variable block sizes is compression (because the resulting block size when compressed will ideally be less than the original).
在压缩以外,支持可变块大小还意味着您可以针对所期望的特定工作量优化块大小,以便改进性能。
Outside of compression, supporting variable block sizes also means that you can tune the block size for the particular workload expected for improved performance.
