缩放不变特征转换(SIFT)是计算机视觉中的一种用来检测和描述图片局部特征的算法。但是,三维建模,野生动物个体识别以及动作匹配。那么不管门的方向发生怎样的变化,这样的点通常在图像的高对比度区域, 应用领域包括目标识别,当需要在一个有很多其他物体的测试图片中定位此物体时,这一从某个训练图像中提取出来的描述就可以用来识别这个物体。 参考资料 { { reflist|refs= 外部链接 Scale-Invariant Feature Transform (SIFT) in Scholarpedia Rob Hess's implementation of SIFT accessed 21 Nov 2012 The Invariant Relations of 3D to 2D Projection of Point Sets, Journal of Pattern Recognition Research (JPRR) , Vol. 3, No 1, 2008.
