TLDR
This work proposes the use of a graph structure to model the relationship between the biometric records in a database and shows the benefits of such a graph in deducing biographic labels of incomplete records, i.e. records that may have missing biographic information.Abstract:
A biometric system uses the physical or behavioural attributes of a person, such as face, fingerprint, iris or voice, to recognise an individual. Many operational biometric systems store the biographic information of an individual, viz., name, gender, age and ethnicity, besides the biometric data itself. Thus, the biometric record pertaining to an individual consists of both biometric data and biographic data. We propose the use of a graph structure to model the relationship between the biometric records in a database. We show the benefits of such a graph in deducing biographic labels of incomplete records, i.e. records that may have missing biographic information. In particular, we use a label propagation scheme to deduce missing values for both binary-valued biographic attributes (e.g. gender) as well as multi-valued biographic attributes (e.g. age group). Experimental results using face-based biometric records consisting of name, age, gender and ethnicity convey the pros and cons of the proposed method.read more

TL;DR: It is concluded that the problem of age-progression on face recognition (FR) is not unique to the algorithm used in this work, and the efficacy of this algorithm is evaluated against the variables of gender and racial origin.

Clustering Millions of Faces by Identity
TL;DR: An approximate Rank-Order clustering algorithm is presented that performs better than popular clustering algorithms (k-Means and Spectral) and an internal per-cluster quality measure is developed to rank individual clusters for manual exploration of high quality clusters that are compact and isolated.

Estimating age, gender, and identity using first name priors

TL;DR: A model uses image-based gender and age classifiers with the cultural context information provided by first names to recognize people with no labeled examples and in turn, the age and gender estimates are improved.

A cascaded convolutional neural network for age estimation of unconstrained faces
TL;DR: Experimental evaluations on three publicly available datasets for age estimation show that the proposed approach is able to reliably estimate the age; in addition, the coarse-to-fine strategy and the error correction module significantly improve the performance.

Image Retagging Using Collaborative Tag Propagation
TL;DR: The proposed image retagging scheme is formulated as a multiple graph-based multi-label learning problem, which simultaneously explores the visual content of the images, semantic correlation of the tags as well as the prior information provided by users.

Annotation propagation in large image databases via dense image correspondence
TL;DR: This work establishes a large graphical model spanning all labeled and unlabeled images, then solves it to infer annotations, enforcing consistent annotations over similar visual patterns, and concludes that the proposed framework outperforms state-of-the-art methods.
