Inducing Predictive Uncertainty Estimation for Face Recognition

no code implementations1 Sep 2020 Weidi Xie, Jeffrey Byrne, Andrew Zisserman

We describe three use cases on the public IJB-C face verification benchmark: (i) to improve 1:1 image-based verification error rates by rejecting low-quality face images; (ii) to improve quality score based fusion performance on the 1:1 set-based verification benchmark; and (iii) its use as a quality measure for selecting high quality (unblurred, good lighting, more frontal) faces from a collection, e. g. for automatic enrolment or display.

Dataset Augmentation for Pose and Lighting Invariant Face Recognition

no code implementations14 Apr 2017 Daniel Crispell, Octavian Biris, Nate Crosswhite, Jeffrey Byrne, Joseph L. Mundy

The performance of modern face recognition systems is a function of the dataset on which they are trained.

Template Adaptation for Face Verification and Identification

no code implementations12 Mar 2016 Nate Crosswhite, Jeffrey Byrne, Omkar M. Parkhi, Chris Stauffer, Qiong Cao, Andrew Zisserman

Face recognition performance evaluation has traditionally focused on one-to-one verification, popularized by the Labeled Faces in the Wild dataset for imagery and the YouTubeFaces dataset for videos.

Nested Motion Descriptors

no code implementations CVPR 2015 Jeffrey Byrne

A nested motion descriptor is a spatiotemporal representation of motion that is invariant to global camera translation, without requiring an explicit estimate of optical flow or camera stabilization.
