SIFT算法由D.G.Lowe 1999年提出,2004年完善总结。后来Y.Ke将其描述子部分用PCA代替直方图的方式,对其进行改进。
2 SIFT 主要思想
SIFT算法是一种提取局部特征的算法,在尺度空间寻找极值点,提取位置,尺度,旋转不变量。
-a method for extracting distinctive invariant features from
images that can be used to perform reliable matching between different views of
an object or scene. The features are invariant to image scale and rotation, and
are shown to provide robust matching across a a substantial range of affine distortion,
change in 3D viewpoint, addition of noise, and change in illumination.
The features are highly distinctive, in the sense that a single feature can be correctly
matched with high probability against a large database of features from
many images.

分而治之方法还可以用于实现另一种完全不同的排序方法,这种排序法称为快速排序(quick sort)。在这种方法中, n 个元素被分成三段(组):左段l e f t,右段r i g h t和中段m i d d l e。中段仅包含一个元素。左段中各元素都小于等于中段元素,右段中各元素都大于等于中段元素。因此l e f t和r i g h t中的元素可以独立排序,并且不必对l e f t和r i g h t的排序结果进行合并。m i d d l e中的元素被称为支点( p i v o t )。图1 4 - 9中给出了快速排序的伪代码,,Delphi

-divide and rule method can be used to achieve an entirely different sort of way This sorting called Quick Sort (quick sort). In this approach, n elements is divided into three (group) : Left of the l e f t, Right of g h i r t and middle m i d e d l. Middle contains only one element. Left of the elements are less than equal to the middle element of the right elements are larger than the middle element. So l and f t e r t h i g of elemental independent sort, and no need to l and f t e r t h i g ranking results merger. M i d e d l The element known as Fulcrum (p i v o t).
