What is Enhanced SIFT Algorithm for Image Matching about?

High-dimensional and complex feature descriptor of SIFT not only occupies a large memory space, but also affects the speed of feature matching. We adopt the statistic feature point’s neighbor gradient way in which the local statistic area is constructed by 8 concentric square ring feature of points-centered, and the pixels gradient as well the statistic gradient accumulated value of eight directions are computed before sorting them in descending order and standardizing them. The new feature descriptor desce
