| Abstract: | To solve the problem of incompletement for the captured images, we improved SIFT feature stitching algorithm to get the whole palmprint images. We proposed LoG-SIFT feature points matching stitching algorithm and designed a strategy for mismatching points remove which can improve the accuracy of matching point. The experimental results showed that the improved algorithm enhanced the palm surface ridge characteristics, significantly increased the number of matching feature points and lowered points matching error rate. |
