Synthesizing Photorealistic Virtual Humans Through Cross-modal Disentanglement

Over the last few decades, many aspects of human life have been enhanced with virtual domains, from the advent of digital assistants such as Amazon's Alexa and Apple's Siri to the latest metaverse efforts of the rebranded Meta. These trends underscore the importance of generating photorealistic visual depictions of humans. This has led to the rapid growth of so-called deepfake and talking-head generation methods in recent years. Despite their impressive results and popularity, they usually lack certain qualitative aspects such as texture quality, lips synchronization, or resolution, and practical aspects such as the ability to run in real-time. To allow for virtual human avatars to be used in practical scenarios, we propose an end-to-end framework for synthesizing high-quality virtual human faces capable of speaking with accurate lip motion with a special emphasis on performance. We introduce a novel network utilizing visemes as an intermediate audio representation and a novel data augmentation strategy employing a hierarchical image synthesis approach that allows disentanglement of the different modalities used to control the global head motion. Our method runs in real-time, and is able to deliver superior results compared to the current state-of-the-art

Complex Monitoring of the Vehicle Movement and Technical State

V rámci této bakalářské práce jsem analyzoval a navrhl systém na komplexní monitorování technického stavu a pohybu vozidel - Fleet Management. Dále jsem implementoval prototyp serverové části systému. Zadavatelem tématu této práce je firma Telematix. Moje bakalářská práce se zabývá analýzou konkurenčních systémů, dále robustním návrhem celého systému, který vyhovuje všem požadavkům zadavatele a následně prototypovou implementací serverové části systému. Výsledek mojí práce bude sloužit jako podklad pro vytvoření rozsáhlého systému na monitorování vozidel ve zmiňované firmě.In this thesis I analyzed and designed a complex system for monitoring the technical condition and the movement of vehicles - Fleet Management. Furthermore, I have implemented a prototype server part of the system. The project owner of the topic of this work is Telematix company. My thesis deals with the analysis of competitive systems, further robust design of the entire system which meets all requirements of the project owner and then a prototype implementation of the server. The result of my work will serve as a basis for the creation of an extensive system for monitoring vehicles in the mentioned company
