UB KinFace Database

Version 2

Last modified: July 31, 2011

Database Description

UB KinFace database is used to develop, test, and evaluate kinship verification and recognition algorithms. It comprises 600 images of 400 people which can be separated into 200 groups. Each group is composed of child, young parent and old parent images. Most of images in the database are real-world collections of public figures (celebrities and politicians) from Internet. To the best of our knowledge, it is the first database that contains all children, young parents and old parents for the purpose of kinship verification.

Figure 1. UB KinFace database illustration on the distributions of four kinship relations over two different race categories.


UB KinFace database can be mainly divided into two parts in terms of race, Asian and Non-Asian, each of which consists of 100 groups, 200 people and 300 images. Typically, there are four kinship relations, namely, “son-father”, “son-mother”, “daughter-father” and “daughter-mother”, as shown in Figure 1. In addition, Figure 2 illustrates the statistics from the perspective of race and kinship relations.

Online Annotation Tool

We developed an online annotation tool to ask voluntary Web visitors to help collect and tag the kinship data. The video demo shows our motivation, the interface of the online annotation tool, and the usage of tagging the relation of people in an image. The tool will be available soon.
