On Hallucinating Context and Background Pixels from a Face Mask using Multi-scale GANs

no code implementations17 Nov 2018 Sandipan Banerjee, Walter J. Scheirer, Kevin W. Bowyer, Patrick J. Flynn

We propose a multi-scale GAN model to hallucinate realistic context (forehead, hair, neck, clothes) and background pixels automatically from a single input face mask.

Fast Face Image Synthesis with Minimal Training

no code implementations5 Nov 2018 Sandipan Banerjee, Walter J. Scheirer, Kevin W. Bowyer, Patrick J. Flynn

Our method samples face components from a pool of multiple face images of real identities to generate the synthetic texture.

Performance of Humans in Iris Recognition: The Impact of Iris Condition and Annotation-driven Verification

no code implementations13 Jul 2018 Daniel Moreira, Mateusz Trokielewicz, Adam Czajka, Kevin W. Bowyer, Patrick J. Flynn

Results suggest that: (a) people improve their identity verification accuracy when asked to annotate matching and non-matching regions between the pair of images, (b) images depicting the same eye with large difference in pupil dilation were the most challenging to subjects, but benefited well from the annotation-driven classification, (c) humans performed better than iris recognition algorithms when verifying genuine pairs of post-mortem and disease-affected eyes (i. e., samples showing deformations that go beyond the distortions of a healthy iris due to pupil dilation), and (d) annotation does not improve accuracy of analyzing images from identical twins, which remain confusing for people.

Domain-Specific Human-Inspired Binarized Statistical Image Features for Iris Recognition

2 code implementations13 Jul 2018 Adam Czajka, Daniel Moreira, Kevin W. Bowyer, Patrick J. Flynn

One important point is that all applications of BSIF in iris recognition have used the original BSIF filters, which were trained on image patches extracted from natural images.

Image Provenance Analysis at Scale

no code implementations19 Jan 2018 Daniel Moreira, Aparna Bharati, Joel Brogan, Allan Pinto, Michael Parowski, Kevin W. Bowyer, Patrick J. Flynn, Anderson Rocha, Walter J. Scheirer

Given a large corpus of images and a query image, an interesting further step is to retrieve the set of original images whose content is present in the query image, as well as the detailed sequences of transformations that yield the query image given the original images.

SREFI: Synthesis of Realistic Example Face Images

no code implementations21 Apr 2017 Sandipan Banerjee, John S. Bernhard, Walter J. Scheirer, Kevin W. Bowyer, Patrick J. Flynn

In this paper, we propose a novel face synthesis approach that can generate an arbitrarily large number of synthetic images of both real and synthetic identities.

The ND-IRIS-0405 Iris Image Dataset

no code implementations15 Jun 2016 Kevin W. Bowyer, Patrick J. Flynn

Image datasets acquired in 2004-2005 at Notre Dame with this LG 2200 have been used in the ICE 2005 and ICE 2006 iris biometric evaluations.
