Abstract

The goal of this paper is to present data structures in 3D face recognition systems emphasizing the role of meshes and depth maps. 3D face recognition systems are still in development since they use different data structures. There is no standarized form of 3D face data. Dedicated hardware (3D scanners) usually provide depth maps of objects, which is not sufficiently flexible data sturcture. Meshes are huge structures and operating on them is difficult and requieres a lot of resources. In this paper, we present advantages and disadvantages of both types of data structures in 3d face recognition systems.
