Improving Automated Latent Fingerprint Identification using Extended Minutia Types
Ram P. Krish, Julian Fierrez, Daniel Ramos +2
Latent fingerprints are usually processed with Automated Fingerprint Identification Systems (AFIS) by law enforcement agencies to narrow down possible suspects from a criminal data…
Expression Recognition Using the Periocular Region: A Feasibility Study
Fernando Alonso-Fernandez, Josef Bigun, Cristofer Englund
This paper investigates the feasibility of using the periocular region for expression recognition. Most works have tried to solve this by analyzing the whole face. Periocular is th…
A Survey on Periocular Biometrics Research
Fernando Alonso-Fernandez, Josef Bigun
Periocular refers to the facial region in the vicinity of the eye, including eyelids, lashes and eyebrows. While face and irises have been extensively studied, the periocular regio…
Periocular Recognition Using CNN Features Off-the-Shelf
Kevin Hernandez-Diaz, Fernando Alonso-Fernandez, Josef Bigun
Periocular refers to the region around the eye, including sclera, eyelids, lashes, brows and skin. With a surprisingly high discrimination ability, it is the ocular modality requir…
Synchronisation of Partial Multi-Matchings via Non-negative Factorisations
Florian Bernard, Johan Thunberg, Jorge Goncalves +1
In this work we study permutation synchronisation for the challenging case of partial permutations, which plays an important role for the problem of matching multiple objects (e.g.…
A modified fuzzy C means algorithm for shading correction in craniofacial CBCT images
Awais Ashfaq, Jonas Adler
CBCT images suffer from acute shading artifacts primarily due to scatter. Numerous image-domain correction algorithms have been proposed in the literature that use patient-specific…
