  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.)
