Scale invariant feature transform (SIFT) proposed by Lowe has been widely and successfully applied to object detection and recognition. However, the representation ability of SIFT features in face recognition has rarely been investigated systematically. In this paper, we proposed to use the person-specific SIFT features and a simple non-statistical matching strategy combined with local and global...
Iris recognition gets more and more attention for its high accuracy rate. However, the iris images are often occluded by eyelids and eyelashes partly and if these noises can't be removed the performance of iris recognition system will be degraded badly. On the other hand low contrast and non-uniform brightness will also increase the difficulty of feature extraction and matching. In this paper an efficient...
