Deep Learning for OCR in GUI
Hamerník, Pavel ; Špaňhel, Jakub (referee) ; Lysek, Tomáš (advisor)
Optical character recognition (OCR) has been a topic of interest for many years. It is defined as the process of digitizing a document image into a sequence of characters. Despite decades of intense research, OCR systems with capabilities to that of human still remains an open challenge. In this work there is presented a design and implementation of such system, which is capable of detecting texts in graphical user interfaces.

Ray Tracing for Electron Microscope
Suchánek, Jan ; Lysek, Tomáš (referee) ; Čadík, Martin (advisor)
This thesis is pointed on simulation of electron microscope. It uses knowledge  from ray-tracing methods and physically based rendering with physics of electron microscopy. The main object of this thesis is to create realistic simulator for electron microscope which can generate satisfying realistic images. This output can be used for another research in range of machine learning or microscope application development. This method should replace long and more expensive way of getting test images from real system for those research activities.
Photorealistic Rendering
Vlnas, Michal ; Lysek, Tomáš (referee) ; Zemčík, Pavel (advisor)
This thesis describes proposal and implementation of a novel global illumination technique using  bidirectional path tracing with multiple importance sampling. In the first part, basic informations and techniques are described to explain photorealistic graphic principles. Also, often used methods solving global illumination are shown. The following part summarizes current state of development. Last two parts are focused on mathematical derivation of the bidirectional path tracing and implementation itself using the CPU.
Atmospheric Efects in WebGL
Brydl, Jaroslav ; Lysek, Tomáš (referee) ; Starka, Tomáš (advisor)
This thesis deals with the simulation and rendering of atmospheric effects in WebGL using Three.js application interface. The principles of functioning and implementation of the effects of altering day and night, clouds, snow,  rain and shadows are described. Effects are mostly implemented with GLSL shaders that allow easy use across different platforms.
Procedural Track Generator
Ončo, Michael ; Lysek, Tomáš (referee) ; Milet, Tomáš (advisor)
This bachelor's thesis deals with procedural generation of an obstacle course for a game in which the player has to overcome these obstacles. It researches suitable ways of generating such course. Within the scope of this research the thesis studies basic traits of noises and grammars. Furthermore it mainly focuses on grammars, L-systems and their attributes. Output of this bachelor's thesis is an application generating the obstacle course, visualizing its geometry using OpenGL and enabling movement through it.
System for Management and Selection of Photos
Blažek, Tomáš ; Lysek, Tomáš (referee) ; Zemčík, Pavel (advisor)
The goal of this bachelor thesis was to create a system for management and selection photos, that should allow users to effectively search in a large number of photos. Criteria of selection include search by elements occurring in the photo, address of place and date of creation photo. Final result is the system implemented in Python language using open source neural network implemented in C language.
Brittle Body Simulation
Chlubna, Tomáš ; Lysek, Tomáš (referee) ; Milet, Tomáš (advisor)
Brittle bodies differ from the rigid ones in the possibility of shattering into small pieces according to the laws of physics. The brittle body simulation therefore uses principles of a general rigid body simulation and requires solutions to the other problems related to object decomposition into fragments and involving these fragments of the original object in the simulation. Description and evaluation of the possible solutions to this problem and a proposal with a reference implementation of such simulation are the goals of this thesis.
WebGL2 Renderer in WebAssembly
Režňák, Pavel ; Lysek, Tomáš (referee) ; Starka, Tomáš (advisor)
This thesis is focused on fast rendering of the 3D scene in a web browser with usage of modern technologies, for instance WebGL and WebAssembly. In this thesis you will find out how to compile an application which was written in C++ language into WebAssembly via Emscripten compilator and how to insert this code into a web page. Futhermore, you will find out how to communicate between C++ language and JavaScript, how to call functions, create instances and how to share memory between them. During design of a rendering core you will learn a few methods how to improve rendering performance. In the end the performance of this technologies is compared.
Interactive Application for Spatial Thinking Training
Mladý, Jakub ; Lysek, Tomáš (referee) ; Tóth, Michal (advisor)
This thesis focuses on the creation of an application that improves logical and spatial thinking. It describes the design, choice of logic games and their following implementation. As the logic games two variations of 3D Tic-Tac-Toe and 3D shape recreation were chosen. The application was implemented in the C++ language using the OpenGL graphics library.
