Multispectral Morphing Dataset

Multispectrl Morphing Dataset (MSMD) comprised of 143 subjects (86 males and 57 females) with varying age groups from 22 to 72 years. The MSMD dataset was collected in multiple sessions to capture visible and multispectral images from 143 subjects.

3D Face Point Cloude Presentation Attack (3D-PCPA) database

3D Face Point Cloude Presentation Attack (3D-PCPA) database acquired using an iPhone 12 Pro Smartphone. The frontal camera of the iPhone 12 Pro, in which the user interacts and captures the 3D point  clouds on their own. The 3D scan was self-captured by the user at 15-20 cms between the face and smartphone. The 3D-PCPA  database comprises bona fide and presentation attack face 3D point clouds to capture the point clouds acquired in multiple  sessions.
