Latent Palmprint Matching
Anil K. Jain,Jianjiang Feng +1 more
TL;DR: This work proposes a latent-to-full palmprint matching system that is needed in forensics and uses minutiae as features and a robust algorithm to estimate ridge direction and frequency in palmprints facilitates minutia extraction even in poor quality palmprints.
Journal ArticleDOI
Latent Fingerprint Matching
Anil K. Jain,Jianjiang Feng +1 more
TL;DR: The experimental results indicate that singularity, ridge quality map, and ridge flow map are the most effective features in improving the matching accuracy.
Journal ArticleDOI

Cheng Jin,Weixiang Chen,Yukun Cao,Zhanwei Xu,Zimeng Tan,Xin Zhang,Lei Deng,Chuansheng Zheng,Jie Zhou,Heshui Shi,Jianjiang Feng +10 more
TL;DR: In a reader study involving five radiologists, the AI system outperforms all of radiologists in more challenging tasks at a speed of two orders of magnitude above them.
Journal ArticleDOI
Combining minutiae descriptors for fingerprint matching
TL;DR: A novel minutiae-based fingerprint matching algorithm that ranks 1st on DB3, the most difficult database in FVC2002, and on the average ranks 2nd on all 4 databases.
Journal ArticleDOI
Fingerprint Reconstruction: From Minutiae to Phase
Jianjiang Feng,Anil K. Jain +1 more
TL;DR: A novel fingerprint reconstruction algorithm is proposed to reconstruct the phase image, which is then converted into the grayscale image, and it is shown that both types of attacks can be successfully launched against a fingerprint recognition system.
