Ray Tracing on CUDA Architecture
Bidmon, Lukáš ; Polok, Lukáš (referee) ; Bařina, David (advisor)
This work presents utilization of CUDA capable graphic cards for ray tracing. First, the classic recursive ray tracing algorithm is presented and necessary math is explained for implemented objects. nVidia CUDA architecture is introduced in next chapter with explained differences from CPU computations. Following is the implementation scheme where modifications necessary for CUDA are discussed. Implementation chapter covers details about flow of the program and memory usage. Finally the CPU and GPU testing results are presented.

GLSL Based Engine
Šlesár, Michal ; Karas, Matej (referee) ; Milet, Tomáš (advisor)
Creating a graphical application running on a GPU typically involves configuring the GPU, creating and configuring the required objects, and then implementing the application's behavior itself. The aim of this work is to create a tool that would automate this configuration using the OpenGL application interface. As a result, the user would not have to waste time configuring and could quickly create and prototype graphics applications. In addition, the created tool adds new functionality to the application that is not native or supported on the GPU, such as working with a mouse and keyboard.

Automated Testing of Image Compressions
Matela, Vít ; Madzin, Matúš (referee) ; Luhan, Jan (advisor)
This thesis deals with the problem of automated testing software for image and video compression developed by the company Comprimato. This work was analyzed in the current testing environment in the company. Based on the resaults of this analysis, I designed and implemented a new automated testing system. Also included is a summary of the economic impact and recommendations for the future purchase of a new test hardware.

GPU Raytracer for OSG
Kantor, Jiří ; Horváth, Zsolt (referee) ; Starka, Tomáš (advisor)
This work describes creation of a simple raytracer for OpenSceneGraph, which performs its operations on the graphics card. Things, that needed to be done in OpenSceneGraph in order to pass data to the GPU and also several ray-triangle intersection methods, are described in this work.

Pixel Interpolation Methods
Mintěl, Tomáš ; Řezníček, Ivo (referee) ; Španěl, Michal (advisor)
This master's thesis deals with acceleration of pixel interpolation methods using the GPU and NVIDIA (R) CUDA TM architecture. Graphic output is represented by a demonstrational application for geometrical image transforms using chosen interpolation method. Time critical parts of the code are moved on the GPU and executed in parallel. There are used highly optimized routines from the OpenCV library, made by the Intel company for an image and video processing.

Exploitation of Graphics Processor as Accelerator - OpenCL Technology
Hrubý, Michal ; Jošth, Radovan (referee) ; Zemčík, Pavel (advisor)
This work deals with the OpenCL technology and its use for the task of object detection. The introduction is devoted to description of OpenCL fundamentals, as well as basic theory of object detection. Next chapter of the work is analysis, with design proposal which takes into consideration the possibilities of OpenCL. Further, there's description of implementation of detection application and experimental evaluation of detector's performance. The last chapter summarizes the achieved results.

Accelerated JPEG Decompression on Graphics Processing Units
Janošík, Ondřej ; Polok, Lukáš (referee) ; Pečiva, Jan (advisor)
This thesis addresses the issue of JPEG decompression, design of algorithms for decompression on graphics cars and their implementation. In more details, it describes specific process of implementation, including possible alternatives and optimizations. It is described in order of JPEG decompression algorithm steps. The aim of this thesis is the reduction of time consumed by uplading textures into graphics unit’s memory using JPEG compressed textures and decompression od the side of graphics card. In addition to time savings, this access reduces processor load, which may be in some cases beneficial.

Realization of supercomputer using graphic card
Jasovský, Filip ; Karásek, Jan (referee) ; Mašek, Jan (advisor)
This master´s thesis deals with realization of supercomputer using graphic card with CUDA technology. The theoretical part of this thesis describes the function and the possibility of graphic cards and desktop computers and processes taking place in the proces sof calculations on them. The practical part deals with creation system for calculations on the graphic card using the algorithm of artificial intelligence, more specifically artificial neural networks. Subsequently is the generated program used for data classification of large input data file. Finally the results are compared.
