Creating a Python-based Automated System for Recognizing Emotions from Facial Expressions.
 Zima, Samuel ; Malik, Aamir Saeed (oponent) ; Hussain, Yasir (vedoucí práce)
This thesis examines facial expression recognition (FER) using deep learning by focusing on its application in devices with limited memory and computational resources. It begins by researching emotions and facial expressions from psychological, biological, and sociological perspectives. The core of this thesis involves the design and implementation of an automated FER system using the FER-2013 dataset. This system uses a customized SqueezeNet architecture enhanced with a simple bypass, dropout layers and batch normalization layers. This system achieves an accuracy of 66.37 % on the FER-2013 dataset. For comparative analysis, this model was compared with a customized VGG16 architecture which achieved an accuracy of 65.09 %. This thesis provides valuable insights into the development of smaller, more efficient machine learning models for FER which are usable in a wide range of devices, including low-performance CPUs and embedded devices.

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.
