MSpalmprints Database

Completely contactless user identification using palm images acquired from the mobile and handheld devices is a challenging research problem. This database has been acquired from over 600 different subjects, which is the largest to-date and is also made available in public domain to advance much needed research in this area. This database also provides two-session long interval (15+ years) palmprint images and includes a large number of images from real world subjects’ manual laborers, farmers, construction workers, etc., whose palm images are acquired under outdoor/ambient illumination.完全无接触式的掌纹识别，系指从移动和便携式设备中获取掌纹图像的研究课题颇具挑战性。本数据库由超过600位不同受试者提供，迄今为止规模最大，并公开发布，以推动该领域急需开展的研究。该数据库还提供了长达两阶段间隔（15年以上）的掌纹图像，并包含大量来自现实世界受试者，如体力劳动者、农民、建筑工人等人的掌纹图像，这些图像是在户外/环境光照条件下采集的。
