    An efficient identity-preserving and fast-converging hybrid generative adversarial network inversion framework
    (Pergamon-Elsevier Science Ltd, 2024) Kale, Ayse; Altun, Oguz
    In this paper, we present a novel Hybrid Generative Adversarial Network (HGAN) inversion framework that enables facial images to be rapidly inverted while preserving identity and personality characteristics. Accurate inversion of facial images requires high precision in computer vision and is critical to the success of future facial manipulations (age progression, regression, accessory, and hair stylization). However, existing methods often fail to preserve the personality characteristics of the real image, negatively affecting the accuracy of manipulations. In this context, our key contribution lies in using a transformer-based strategy to initiate the generator, which effectively models spatial relationships for detailed image processing. This approach is innovative because it leverages transformer structures to enhance image inversion tasks. Additionally, we introduce a novel loss function to enhance convergence speed and reliability, ensuring high accuracy in identity and personality trait preservation. Experimental results show that our method achieves a reconstruction accuracy of 93% and improves inversion time by 86%. This advancement could significantly impact facial manipulation technologies, laying the foundation for a technological breakthrough with potential applications in secure digital authentication systems and personal data protection. Our method may have a significant impact on privacy and security in future studies, contributing to the development of secure digital authentication systems and enhancing the protection of personal data. Therefore, our work is crucial for advancing the field of facial image manipulation and ensuring the privacy and security of personal data.

    Face age synthesis: A review on datasets, methods, and open research areas
    (Elsevier Sci Ltd, 2023) Kale, Ayse; Altun, Oguz
    Face age synthesis is the determination of how a person looks in the future or the past by reconstructing their facial image. Determining the change in the human face over the years is a critical process for cross-age face recognition systems in forensic issues such as finding missing people and fugitive criminals. Therefore, it is a subject that has attracted attention in recent years. With the implementation of deep learning methods, better quality and photo-realistic images began to be produced. However, researchers continue to improve both aging accuracy and identity preservation requirements. We group the studies in the literature under two categories: classical methods and deep learning methods. We review both categories in the methods used, evaluation methods, and databases.& COPY; 2023 Elsevier Ltd. All rights reserved.
