A SIFT-based contactless palmprint verification approach using iterative RANSAC and local palmprint descriptors

作者：

Highlights：

• An isotropic filer based preprocessing method is devised to enhance palmprint image.

• An iterative RANSAC algorithm is proposed to refine the matched SIFT points.

• Local palmprint descriptors are extracted to further refine the matched SIFT points.

• The proposed matching refinement can improve the performance of SIFT based approach.
