User Interface for HDR Tone Mapping System
Jedlička, Jan ; Špaňhel, Jakub (referee) ; Čadík, Martin (advisor)
The goal of this thesis is to improve graphical user interface of Tone Mapping Studio(TMS) program. This program is being developed on the Faculty of Information Technology(FIT), Brno University of Technology (BUT) by doc. Ing. Martin Čadík, PhD. The current program is using framework Qt3 , which is old and not compatible with modern libraries. This program has to be rewritten to support current version Qt5. I will analyze other programs in the area of working with High Dynamic Range (HDR) images and video. Changes for improving the interface will be proposed and UX tests will be done. Second part will consist of comparing plug-ins for converting images to grayscale that already exists in TMS.
Object Tracking in Panoramic Video
Ambrož, Vít ; Hradiš, Michal (referee) ; Čadík, Martin (advisor)
The master thesis maps the state of the art of visual object tracking in panoramic 360° video. The thesis aims to reveal the main problems related to visual object tracking and moreover focuses on their solution in panoramic videos. In the study of the existing approaches was found that very few solutions of visual object tracking in equirectangular projection of panoramic video have been implemented so far. This thesis therefore presents two improvements of object tracking methods that are based on the adaptation of equirectangular frames. In addition, this thesis brings the manually created dataset of panoramic videos with more than 9900 annotations. Finally the detailed evaluation of 12 well known and state of the art trackers has been performed for this new dataset.
Realistic Visualization of Snow
Chukir, Patrik ; Polášek, Tomáš (referee) ; Čadík, Martin (advisor)
This diploma thesis follows visualization of snow formations, which are called penitentes. This work includes also collecting the data needed to derive the optical properties of the penitentes material. Which are different phases between snow and ice. For visualization method is used Progressive Transient Photon Beams, that this work implements with the help of SmallUbpb.
Volumetric Segmentation of Dental CT Data
Berezný, Matej ; Kodym, Oldřich (referee) ; Čadík, Martin (advisor)
The main goal of this work was to use neural networks for volumetric segmentation of dental CBCT data. As a byproducts, both new dataset including sparse and dense annotations and automatic preprocessing pipeline were produced. Additionally, the possibility of applying transfer learning and multi-phase training in order to improve segmentation results was tested. From the various tests that were carried out, conclusion can be drawn that both multi-phase training and transfer learning showed substantial improvement in dice score for both sparse and dense annotations compared to the baseline method.
Mobile Application Rendering Digital Elevation Models in Real Time
Hejl, Radim ; Tomešek, Jan (referee) ; Čadík, Martin (advisor)
This bachelor thesis deals with terrain rendering on mobile device in realtime. It focuses on current developement of applications in operating system Android, especially rendering of graphics using OpenGL ES. Based on this information and actual state of existing solutions, there is designed, implemented and tested resulting application, that renders surrounding terrain and navigating in it using sensors of device.
Algorithms for Automatic Spherical Image and Video Cropping
Ivančo, Martin ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
Cieľom tejto práce je priniesť detailný pohľad na doterajší prieskum v oblasti sférických videí. Konkrétne sa táto práca zameriava na problém tvorby videa s normálnym zorným poľom zo sférického videa pre potreby zobrazovania. Prináša tiež implementáciu niektorých dostupných metód. Doteraz boli predstavené tri metódy v štyroch článkoch, ktoré riešia tento problém. Všetky priniesli zaujímavé výsledky a táto práca sa dvomi z nich zaoberá hlbšie. Táto práca tiež prináša základnú metódu využívajúcu overené metódy automat- ického orezu obrazu. Táto metóda je využitá na porovnanie so skúmanými metódami, u ktorých zvýrazní ich vylepšenia ale aj nedostatky. Na základe porovnania metód pomocou užívateľského experimentu táto práca usudzuje, že najlepšou zo skúmaných metód pre túto úlohu je upravená varianta metódy od Pavel et al. [14], predstavená v tejto práci.
Mobile Application for Automatic Recording of Chess Games
Jiruška, Adam ; Bobák, Petr (referee) ; Čadík, Martin (advisor)
This thesis is focused on making application for mobile devices, which records progress of chess game. This is achieved by image recognition on input from camera. Chess figures are classified by neural network. Usage of application is during training or real matches to record games and then for analyzing these games. For analyzing, my application offers record in standard algebraic notation. User can also add notes to every game.
Simulation of Snow and Ice Features
Čech, Ondřej ; Polášek, Tomáš (referee) ; Čadík, Martin (advisor)
This project focuses on simulation of formation of glaciers known as Penitentes. It is based on mathematical model of formation of these structures by M. D. Betterton. Implementation is done in C++ programming language, and the result is exported as bitmap image containing heightmap, which can be rendered using Blender.
Web App for Capturing and Sharing New Shots of Historical Photographs
Mencner, Pavel ; Maršík, Lukáš (referee) ; Čadík, Martin (advisor)
This bachelor's thesis deals with design and implementation of the web application used for capturing and sharing new shots of the historical photographs also known as rephotographs. Product application is realised in JavaScript programming language. Server side is build on the Node.js platform and use Express.js framework and NoSQL database MongoDB. Client side is realised as single page application build on Angular 2 framework and communicates with server side via REST interface.
Dynamic Image Presentations Using Depth Maps
Hanzlíček, Jiří ; Brejcha, Jan (referee) ; Čadík, Martin (advisor)
This master's thesis focuses on the dynamic presentation of still photography using a depth map. This text presents an algorithm that describes the process of creating a spatial model which is used to render input photography so that the movement of virtual camera creates parallax effect due to depth in image. The thesis also presents an approach how to infill the missing data in the model. It is suggested that a guided texture synthesis is used for this problem by using rendering outputs of the model themselves as guides. Additional information in model allows the virtual camera to move more freely. The final result of the camera movement can be saved to simple video sequence which can be used for presenting the input photography.
