尺度不变特征变换（Scale-invariant feature transform或SIFT）是一种计算机视觉的算法去查找并描述图像的局部特征。sift比较通俗的详解，比一般的详细。英文-Scale Invariant Feature Transform (Scale-invariant feature transform, or SIFT) is a computer vision algorithm to find and describe the local features of th

尺度不变特征转换算法（sift）在空间尺度中寻找极值点，具有位置、尺度、旋转不变性，可正常运行-Scale Invariant Feature Transform algorithm (sift) looking at the spatial scale of the extreme points, with the position, scale and rotation invariance, the normal operation
