The impact of facial expressions on 3D face recognition.
Kováč, Peter ; Goldmann, Tomáš (oponent) ; Pleško, Filip (vedoucí práce)
The thesis "The impact of facial expressions on 3D face recognition" focuses on studying the effect of facial expressions on the accuracy of 3D face recognition. The first chapters explore various 3D modeling techniques and their applications, including 3D Morphable Models (3DMMs), blendshape models, and neural network-based methods like FLAME (Faces Learned with an Articulated Model and Expressions). The thesis then presents a new approach for reconstructing 3D face models from 2D images and proposes an evaluation framework to measure the impact of facial expression changes on 3D face recognition. Experimental results demonstrate how different expressions, such as anger, happiness, and fear, influence recognition accuracy. The findings of this work contribute to a deeper understanding of facial expressions’ role in 3D face recognition and propose potential improvements for enhancing recognition systems.
