BVC Dataset
BVC-UNN-Face data
A database of Nigerian face images - BVC-UNN-face data, was collected by the Biometrics Vision and Computing (BVC) group at the University of Nigeria in 2018. We are making the BVC-UNN-face data free and publicly available with the spirit of promoting the sharing of academic knowledge. The BVC group through the University of Nigeria retains ownership and copyright of the BVC-face dataset. The BVC-face data is distributed via the University of Notre Dame.
A formal request is required to use the BVC-face data. In other words, a researcher requesting for the dataset is required to fill a formal agreement and return to us via his/her institutional email.
BVC-UNN-Body data
A database of Nigerian body images - BVC-UNN-body data, was collected by the Biometrics Vision and Computing (BVC) group at the University of Nigeria in 2018. We are making the BVC-UNN-body data free and publicly available with the spirit of promoting the sharing of academic knowledge. The BVC group through the University of Nigeria retains ownership and copyright of the BVC-body dataset. The BVC-body data is distributed via the University of Notre Dame.

Algorithms
Fingerprint binarization algorithm
Fingerprint binarization codes are available on my Github link: https://github.com/OgeNI/Fingerprint_Process_Enhance_Binarize
The codes in this repository carry out an adaptive contrast enhancement and binarisation of fair and poor qualities plain and rolled fingerprints with large regions of low quality, prior to orientation field estimation. The algorithm effectively enhances smudged and faded ridges uniformly in recoverable regions, based on values of statistical variables computed locally in each region. The preprocessing algorithm employs a locally adaptive thresholding approach resulting in enhanced binarised images.
