作为一种匹配能力较强的局部描述算子,SIFT算法的实现相当复杂,但从软件开发的角度来说,只要会使用其中几个比较重要的函数就行了。这里要感谢David Lowe这个大牛,不但提供了一种强悍的特征匹配算法,还给出了C++的实现代码,后来有人用C#实现了这个算法,需要的朋友可到网上自行下载。

算法描述
SIFT特征不只具有尺度不变性,即使改变旋转角度,图像亮度或拍摄视角,仍然能够得到好的检测效果。整个算法分为以下几个部分:
(1)构造尺度空间:DoG尺度空间
(2)检测DoG尺度空间极值点
(3)去除不好的特征点
(4)给特征点赋值一个128维的方向参数。每个关键点都包含三个信息:位置、尺度和方向。
(5)关键点描述子的生成:
首先将坐标轴旋转为关键点的方向,以确保旋转不变性。以关键点为中心取8×8的窗口。
(6)最后进行特征匹配。(Algorithm descr i
