Depth Map from a Pair of Images
Raab, Filip ; Španěl, Michal (referee) ; Přibyl, Bronislav (advisor)
This thesis describes the process of creating a depth map. It is based on creating disparity map. In theoretical chapters are described basic methods creating disparity map and its relationship to depth map. Here is made decision about choice implemented method, which is in detail described. In practical chapters is description of process creating followed by testing of results. At the end is summary all facts about implemented method, implementation and possible continuation of project.

Cloud Solution for 3D Models Processing
Klemens, Jakub ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This thesis deals with the possibilities of processing 3D models in cloud applications. A C++ library called Cloud3D has been designed and implemented. The resulting library is used to quickly create client-server applications. The library is divided into three separate parts: Client, Service Provider and Load Balancer. The service provider runs in the cloud and provides 3D model processing services to client applications. The biggest advantage of Cloud3D is the ease of creating new applications with its help. Other benefits include scalability, assured implementation of look-a-side Load Balancer, and security ensured by the use of SSL certification.

Doors and Door Handle Localization for PR2
Botka, Roland ; Španěl, Michal (referee) ; Kapinus, Michal (advisor)
The aim of this work is to design and create a module for locating doors and handles for the robotic platform PR2. Finding the doors should be done separately, which means that the robot finds a door in the room without assistance. Handle position is stored in a file which the data are read from based on the AR code affixed to the door. The result of this module should be a program for the Robotic operating system that will locate the door in the room, and give information about them. These informations will be the basis for the work of another module, which open the door. The final test took place in a faculty robotic laboratory

Interactive Interface for Robot Remote Control for Android
Robotka, Vojtěch ; Materna, Zdeněk (referee) ; Španěl, Michal (advisor)
The development of autonomous robots has made a significant progress and first personal robots for common use start to appear. To use this robots, we need to develop applications and user interfaces to interact with them. The goal of this project is to make a universal interface for robot remote control. This work focuses on robots based on the ROS platform. This gives the final application a potential of use on other robotic projetcs running on ROS. The designed remote interface accomplishes two main purposes. The first is to show important data in a context of a 3D scene to help user understand the state of the controlled robot. And the second goal is to allow the user execute some basic manipulation with the robot. The final application was successfully adapted and tested on experimental robots Care-O-Bot and Turtlebot.

Acceleration of 3D Image Processing Using GPU
Jochlík, Jakub ; Klepárník, Petr (referee) ; Španěl, Michal (advisor)
This thesis proposes a solution for acceleration of large 3D image data filtering by using the compute power of graphic cards. This solution uses OpenCL platform to dedicate all necessary computation onto graphical core of the graphic card and furthermore optimize this process using on-board local memory. Design and implementation of the mentioned approach is mainly focused on Sobel Operator.

Displaying 3D Graphics in Web Browser
Mahr, Lukáš ; Klepárník, Petr (referee) ; Španěl, Michal (advisor)
This thesis deals with design and implementation of an interactive 3D model viewer in a web browser. Aim of the thesis is to faithfully present industrial and commercial products to potential customers of the product. The final application allows to decompose the object into individual parts and a special semi-transparent edge-highlighted display. The WebGL web technology and the Three.js library are used for implementation.

Road Detection for Autonomous Car
Komora, Matúš ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
his thesis deals with detection of the road adjacent to an autonomous vehicle. The road is recognition is based on the Velodyne LiDAR laser radar data. An existing solution is used and extended by machine learning - a Support Vector Machine with online learning. The thesis evaluates the existing solution and the new one using a KITTI dataset. The reliability of the road recognition is then computed using F-measure.

Automated Identification of Graphical UI Elements for Robotic Quality Assurance
Válek, Lukáš ; Herout, Adam (referee) ; Španěl, Michal (advisor)
Tato práce se zabývá problematikou analýzy obrazovek grafického uživatelského rozhraní (GUI) pomocí konvolučních neuronových sítí (CNN) a metod počítačového vidění. Cílem této práce je vytvořit systém, který automaticky identifikuje GUI elementy na základě piktogramových a textových informací pro detekované prvky ve vstupním obrázku. K~vývoji systému byla použita kombinace EfficientNetB1 CNN, OCR a tradičních metod počítačového vidění. K trénování CNN byla použita vlastní datová sada, která obsahovala 120 tisíc piktogramů. Byl vytvořen sémantický slovník UI prvků, který dále využívá text detekovaný pomocí OCR. Nakonec byl vytvořen podsystém pro analýzu GUI hierarchie, který slouží k detekci a sémantické kategorizaci oblastí GUI. Výsledný systém automaticky klasifikuje detekované piktogramy, navrhuje další třídy na základě textu a rozděluje GUI obrazovku do hierarchických sekcí. Systém dosahuje 81,1% přesnosti identifikace UI prvků a v průměru zanalyzuje jednu obrazovku za 0,6 sekundy. Systém automatizuje identifikaci UI prvků, čímž umožňuje zaměstnancům věnovat se jiným činnostem. V budoucnu lze tento systém dále rozvíjet, aby sloužil jako základ pro automatické exploratorní testování.

Synthetic Image Noise Generators
Sigmund, Pavel ; Herout, Adam (referee) ; Španěl, Michal (advisor)
In this work I'm implementing library for generating basic kinds of noises which I'm also using for generating procedural textures and height maps . I have focused on K. Perlin method frequently used for making textures with nature-based motives, like wood, marble or clouds. I've implemented this method into the library to make 2D and 3D textures. Library used for generating noises, thanks to its variability, is not ment as a source of generated pseudo-random numbers for K. Perlin method only, but we can also use it as a tool to add a noise to any kind of data.

Object Detection Using Kinect
Němec, Lukáš ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This paper address the problem of object recognition using Microsoft Kinect in the fi eld of computer vision. The objective of this work was to evaluate current methods of detection of objects using depth map (RGB-D sensor). The work deals with the enviroment of point cloud and Viewpoint Feature method. It also describes the use of binary classifi er in the context of object recognition. Object detection was implemented and performed experiments with it.
