暂无分享,去创建一个
A formula is provided to compute the number of new blocks resulting from the decomposition induced by a shift of a single quadtree node of arbitrary size by an arbitrary amount. A precise calculation is also presented for the average number of BLACK nodes required to represent a square of width 2 m in a region quadtree.
