How much do we indent a subblock?
一个子块要缩进多少？
The SPS (Subblock Partition Scheme) based on modulate constellation in PTS method is adopted.
采用了基于调制星座集的PTS子序列分组方法。
It is proved that for a image subblock with a single straight edge, the DCT coefficient. energy compaction orientation and the spatial edge orientation are not always orthogonal.
通过理论推导及事例分析证得含平直单边缘图像子块，其DCT变换系数能量并不总是集中分布在与其空间边缘走向垂直的方向上。
