这个方法有两个好处。
（ a ）虽然只是一个半径差逼近，很容易找到最高在一个小蓄电池，因为通过降低 隐平滑做的蓄电池。（ b ）在同一时间处理时间搜索减少
(Pattern Recognition and Image Procesing Group.
The size of the accumulator is varied as hierarchical voting is performed. This
has two advantages.
[a] While the radius is only a poor approximation, it is easier to find the maximum
in a small accumulator and because by means of the downsampling
implicit smoothing is done to the accumulator.
[b] At the same time processing time for the search is reduced.)

BruteSearch
K-nearest neighbors 搜索 聚类时经常使用的一种方法 国外网站转载( The following utilities are provided:
- Nearest neighbor
- K-Nearest neighbors
- Radius Search
They al supports N-dimensions and work on double, it is possible to choose if return the distances.
Here is a time comparison with a vectrized m-code:
N=1000000 number of reference points
Nq=100 number of query points
dim=3 dimension of points
k=3 number of neighbor
