 Biometric identification is an emerging technology that can solve security problems in our networked society. A few years ago, a new branch of biometric technology, palmprint authentication, was proposed [1] whereby lines and points are extracted from palms for personal identification. In this paper, we consider the palmprint as a piece of texture and(More)
—Finger-vein recognition as a non-contact biometric technique has its inherent superiority on accuracy, speed, sanitation, maintenance and security. However, we found that due to posture changes when acquiring finger images, the discrepancy between different images from the same finger greatly lowers the performance of the entire system. In this paper, we(More)
Palmprint identification provides a new technique for personal authentication. Previous research on palmprint identification mainly focuses on feature extraction and representation (Pattern Recognition 33(4) (1999) 691). But a crucial issue, palmprint alignment, is not addressed. Palmprint alignment involves moving and rotating the palmprints to locate at(More)
The scorpion toxin, charybdotoxin (ChTX), is the first identified peptide inhibitor for the large-conductance Ca2+ and voltage-dependent K+ (BK) channel, and the chemical information of the interaction between ChTX and BK channel remains unclear today. Using combined computational methods, we obtained a ChTX-BK complex structure model, which correlated well(More)
