Distinctive Image Features from Scale-Invariant Keypoints

Web2 sift算法. 尺度不变特征变换（sift）是一种计算机视觉的算法，用来侦测和描述影像中的局部性特征。sift算法主要由构建影像尺度空间、关键点精确定位、确定关键点方向、生成关键点描述符4个步骤构成[6]。 2.1 构建影像尺度空间及特征点精确定位 Webdetector developed by Lowe in 2004 [3]. Although SIFT has proven to be very efficient in object recognition applications, it requires a large computational complexity which is a major drawback especially for real-time applications [3, 4]. There are several variants and extension of SIFT which have improved its computational complexity [5-7].
