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.

Image segmentation on GPU
Bravenec, Tomáš ; Mego, Roman (referee) ; Frýza, Tomáš (advisor)
Bachelor thesis is focused on using graphical processing units for parallel data processing, specifically on image processing. Main focus of this thesis is determining time difference in image processing using graphical processing unit and classic approach on processor. Another focus is accessing webcam and processing of captured frames.

General Processing on Graphics Processing Units for Industrial Systems
Lukačovič, Martin ; Mašek, Jan (referee) ; Krkoš, Radko (advisor)
The thesis deals with the abilities of graphics processors for GPGPU. It contains historical solutions to contemporary design. There are also described graphics processors from the largest manufacturers of this time, their focus and goals in the future. For algorithms implementation using GPU, there are necessary APIs that offer various possibilities of execution. In addition to the CPU and GPU universal heterogeneous computing, there are alternatives such as FPGA and DSP so it is necessary to consider the price and energy cost. Part of the work is devoted to the communication possibilities with the hardware and advanced memory approaches. For demonstrating parallel computing an implementation of matrix multiplication in OpenCL was realized.

Geometrical Image Transforms
Němeček, Petr ; Řezníček, Ivo (referee) ; Španěl, Michal (advisor)
This master's thesis deals with acceleration of geometrical image transforms using the GPU and NVIDIA (R) CUDA TM architecture. Time critical parts of the code are moved on the GPU and executed in parallel. One of the results is a demonstrational application for performance comparison of both architectures: the CPU, and GPU in combination with the CPU. As a reference implementation, there are used highly optimized routines from the OpenCV library, made by the Intel company.

Programming CUDA with C#
Zajíc, Jiří ; Kačic, Matej (referee) ; Jurnečka, Peter (advisor)
This master's thesis is focused on GPU accelerated calculations on NVidia graphics card. CUDA technology is used and converted to implementation on a .NET platform. The problem is solved as a compiler from C# programing language to NVidia CUDA language with expression atrributes of C# language that preserves the same semantics of actions. Application is implemented in C# programing language and uses NRefactory, the open-source library.

Object Detection on GPU
Macenauer, Pavel ; Polok, Lukáš (referee) ; Juránek, Roman (advisor)
This thesis addresses the topic of object detection on graphics processing units. As a part of it, a system for object detection using NVIDIA CUDA was designed and implemented, allowing for realtime video object detection and bulk processing. Its contribution is mainly to study the options of NVIDIA CUDA technology and current graphics processing units for object detection acceleration. Also parallel algorithms for object detection are discussed and suggested.

Paralelized image processing library
Fuksa, Tomáš ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
This work deals with parallel computing on modern processors - multi-core CPU and GPU. The goal is to learn about computing on this devices suitable for parallelization, define their advantages and disadvantages, test their properties in examples and select appropriate tools to implement a library for parallel image processing. This library is going to be used for the vanishing point estimation in the path finding mobile robot.

Computations on Graphics Cards
SVOBODA, Aleš
Purpose of this work is to show possibility of using graphics card not just for 3d graphics but also for computations which were for a long time just a domain of CPU. In the first part we are looking at what graphics card is as well as APIs used for their programming. Second part shows us OpenCL API on an example. Last part is measurement of performance between CPU and GPU.

Hardware for Small Companies
Bešta, Václav ; Měsíček, Libor (advisor) ; Pitka, Lukáš (referee)
I have been encountering the concept of hardware for many years and I am really interested in it. That is why I have decided to deepen my knowledge in this subject field and to write the thesis named Hardware for Small Companies. At the present time, when the modern technologies are used in many departments, is hardware becoming more and more demanded goods. Also the fact, that hardware as a structural unity cannot be upgraded to more efficient unit, may assist. If the user wants to upgrade one concrete part, he can't do anything else than to buy a new, upgraded unit. The spectrum of the hardware conception is very wide and I pursue mainly the part, which can be used in the small company environment and its accessibility at the Czech market. Then I mention the history of hardware and its prominent world producers. Writing the theoretical part, I used web-based sources and the scientific literature, that is concerned with the conception of hardware the most. Writing the practical part, I made use of the knowledge that I got from my studies and from the online offers of the prominent hardware suppliers. The main contribution of the thesis is the project described in the practical part. This project will serve as a rough basis for getting a capital grant for the creation of the new training center in the pension Dubina in Litoměřice.
