Detection of Vehicles in Image and Video
Petráš, Adam ; Zemčík, Pavel (referee) ; Špaňhel, Jakub (advisor)
This bachelor thesis is focused on vehicle detection. The thesis deals with the method of vehicle detection using convolutional neural networks, their structures and models. All scripts were implemented using python programming language with Tensorflow Object Detection API interface. The first part of this thesis was devote to the structures of popular neural networks and models of detection neural networks. The next chapter deals with the most famous frameworks that are used for machine learning. Three neural network models were selected and trained on the COD20K dataset. The result of this thesis is statistics that discuss the efficiency and performance of each model on trained dataset and compare performance without displaying video on Nvidia RTX 2060, where the performace archieved by SSD MobileNet V2 network was 300FPS and Nvidia Tegra TX2 8GB, whose performace reached almost 44FPS.

Detection and Classification of Road Users in Aerial Imagery Based on Deep Neural Networks
Hlavoň, David ; Hradiš, Michal (referee) ; Rozman, Jaroslav (advisor)
This master's thesis deals with a vehicle detector based on the convolutional neural network and scene captured by drone. Dataset is described at the beginning, because the main aim of this thesis is to create practicly usable detector. Architectures of the forward neural networks which detector was created from are described in the next chapter. Techniques for building a detector based on the naive methods and current the most successful meta architectures follow the neural network architectures. An implementation of the detector is described in the second part of this thesis. The final detector was built on meta architecture Faster R-CNN and PVA neural network on which the detector achieved score over 90 % and 45 full HD frames per seconds.

Detection and Classification of Vehicles for Embedded Platforms
Skaloš, Patrik ; Hradiš, Michal (referee) ; Špaňhel, Jakub (advisor)
Táto práca hodnotí kompromisy rýchlosti a presnosti najmodernejších detektorov objektov YOLOv8 pre detekciu vozidiel v snímkoch z monitorovacích kamier na vstatných a nízkovýkonných zariadeniach. Modely YOLOv8 rôznych veľkostí, vrátane jedného s efektívnou sieťou MobileNetV2 na extrakciu príznakov a modelu YOLOv8-femto s menej ako \num{60000} parametrami, boli testované na šiestich zariadeniach, vrátane troch vstavaných platforiem z rodiny NVIDIA Jetson a počítačom Raspberry Pi 4B s nízkou výpočtovou silou. V práci boli zohľadnené rôzne faktory ovplyvňujúce výkonnosť modelov, ako napríklad ich kvantizácia, rozlíšenia vstupu, inferenčné knižnice a veľkosti dávok počas inferencie. Táto štúdia poskytuje užitočné informácie k vývoju a nasadeniu detektorov vozidiel na širokú škálu zariadení, od nízkovýkonných procesorov po špecializované vstavané platformy.
