Smoke and Fire Detection in Video Sequences
Havelka, Robert ; Juránek, Roman (referee) ; Španěl, Michal (advisor)
This master's thesis deals with fire detection in videosequences. Attention is paid to the known characteristics of fire and basic principles of existing solutions which deal with this issue. The thesis also describes design, implementation and testing of a fire detector that is based on the recognition of suspicious areas by fire color modeling, combined with detection of motion and light intensity variations.
Scene Ilumination by Photon Mapping Method
Hübner, Lukáš ; Španěl, Michal (referee) ; Kršek, Přemysl (advisor)
This thesis deals with the estimation of global illumination of a~scene. Global illumination is expressed as a~physical simulation in connection with illumination methods used in current computer graphics. In the practical part there is expressed an implementation of global illumination estimation using photon maps.
Interactive Interface for Robot Remote Control
Lokaj, Tomáš ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This work deals with the interactive interface for remote controlled robots and examines some of the existing visualization and simulation tools and robotic platforms. It also designs and implements interactive elements suitable for representation of detected objects, such as bounding box or billboard, and proposes interactive elements to eliminate some of the problems associated with remote control of the robot, such as bad perception of distances and the orientation in the environment. The interactive interface is implemented in the Robot Operating System using offered means for visualization, communication and operations management. Graphics primitives are represented by Interactive Markers that, in addition to the visualization, offers also possibilities of interaction. With these markers, a simple tool for controlling the movement of the robot is designed.
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.
Interaction with Old Maps on Mobile Devices
Urban, Martin ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
The goal of this thesis is to experiment with the latest web technologies and to design new process for mobile application creation. It is possible to create multiplatform applications which are almost unrecognizable from native applications by proposed procedures.  It is focused on performance and native behaviour of the user interface in this thesis. Described practices are demonstrated on application designed for work with historical maps, which is able to show maps from historical archives whole over world real-time. Rapid acceleration has been showed on the demonstrative application compared to standard process of creation of web applications.
User Interaction with Objects in 3D Space
Studeník, Pavel ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
This thesis is focused on interaction with object in 3D environment. For detection of user is used the Microsoft Kinect device. Interaction is based on touchless control which is inspirated by reality.  Behaviour of designed solution is researched in experiments and some application is created for demonstration of functionality.
My 3D Printer
Mošner, Ladislav ; Klepárník, Petr (referee) ; Španěl, Michal (advisor)
This thesis deals with the topic of 3D printing. The primary aim was to build a real printer with a stiff construction minimizing clearance, which affects the accuracy and quality of printing. The design of the 3D printer and its parts was highly influenced by the RepRap project, especially by the Rostock printer using the delta kinematics and Fused Deposition Modeling. The printer electronics is based on the Arduino Mega 2560 platform running a modified Marlin firmware. It uses a newly designed extruder that should prevent a filament from melting in a guide tubule due to a large heatsink. The experiments carried out show that the accuracy of the printer is within +-0,1 mm.
3D Objects Detection in Images
Bordovský, Gabriel ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This bachelors thesis deals with detection of a known 3D object in images and its pose estimation. The method uses the ORB-type keypoints and their location on the surface of a bounding box. By using solve of PnP problem a pose of the object is obtained using the points 2D coordinates from the image and the 3D coordinates of the very points from the registered model. This thesis expands a detection method for simple box-shaped objects, which is a part of OpenCV library, for the usage on more complex objects. In experiments, the detector reached a detection success rate of 85 % and the computed pose matches the real one approximately for 88 %.
3D Shape Interpolation
Zouhar, Marek ; Polok, Lukáš (referee) ; Španěl, Michal (advisor)
This thesis deals with creation of a~tool for progressive interpolation of shape of a~3D polygonal mesh. Used methods take inspiration mainly in technique Manual Landmarks and use parametrization of an object to a~sphere. The result of this thesis is an addon for an open-source modelling program Blender, which automatically creates an animation of shape deformation based on two input models.
Deep Learning for Image Recognition
Kozel, Michal ; Španěl, Michal (referee) ; Hradiš, Michal (advisor)
Neural networks are currently state-of-the-art technology for speech, image and other recognition tasks. This thesis describes basis properties of neural networks and their learning. The aim of this thesis was to extend Caffe framework with new learning methods and compare their performance on Cifar10 dataset. Namely RMSPROP and normalized SGD
