A Review on Essential Resources Utilized for Face Recognition

In facial identification tasks, face alignment is the most important aspect. Utilizing localization of various face landmarks for structural face normalization, in particular, has proven to be extremely reliable, significantly enhancing recognition performance. This article presents a survey on popular repositories such as BioID face repository, XM2VTS repository, BUHMAP-DB repository, MUCT face repository, and PUT face repository and their characteristics. Along with that, the tools are essential for building applications concerning facial recognition in real-world aspects. The popular part of applications for face recognition such as localization of landmarks, estimating the facial position, and Multi-directional viewable face recognition are also discussed. Of all the existing repositories, AFLW is highly popular due to the existence of a high number of faces in real-world aspects.
