Optimized Ray Tracing
Hrubý, Michal ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor's thesis analyzes the problem of ray tracing and its optimizations. It describes mathematical principles of ray tracing and intersection searching of objects in scene and ray.  It also analyzes different shading models and efficient building of kd-tree for dividing scene objects. The thesis focuses on design and implementation of multiplatform and easily extensible ray tracing application in C++.
Face Detection
Štrba, Miroslav ; Juránek, Roman (referee) ; Hradiš, Michal (advisor)
This bachelor thesis contains overview of actual face detection methods using classifier. It also contains description of creating system for face detection. There are described different methods for classifier training in first part. There is analysis, which preceded creation of system focused on black-and-white picture, in second part. Implemented system is using WaldBoost algorithm and Haar features. There is option to use particle filter in video.
Line Detection with Different Size
Váňa, Lukáš ; Hradiš, Michal (referee) ; Beran, Vítězslav (advisor)
This Bachelor Theses deals with question of the location of the set thicknesses of lines in the picture. It summarizes theoretical basis and procedures for the elaboration of the incoming signal and the Theory of the edge detection. It mentioned current known methods for lines detection in the picture. By the assist of these methods, extended of another known procedures, this theses suggested algorithm, able to detect line of the set thickness in the picture. It describes also suggestion of the realization of the application, which demonstrates utility of the created algorithm. The application is the programming part of this Theses.
Boosting and Evolution
Mrnuštík, Michal ; Juránek, Roman (referee) ; Hradiš, Michal (advisor)
This thesis introduces combination of the AdaBoost and the evolutionary algorithm. The evolutionary algorithm is used to find linear combination of Haar features. This linear combination creates the feature to train weak classifier for AdaBoost. There are described basics of classification, Haar features and the AdaBoost. Next there are basic information about evolutionary algorithms. Theoretical description of combination of the AdaBoost and the evolutionary algorithm is included too. Some implementation details are added too. Implementation is tested on the images as part of the system for face recognition. Results are compared with Haar features.
Video-Based Human-Computer Interface
Wiewiorka, Petr ; Hradiš, Michal (referee) ; Španěl, Michal (advisor)
This bachelor's thesis descripts a way of controlling a computer by hand gestures. Picture is taken from web camera, in which search for a position of hand in picture and recognize gesture. The gesture signal controls a computer. I use the OpenCV library for a work with picture. At the end are output pictures.
Hand Computer Controlling
Matějíčka, Miloš ; Hradiš, Michal (referee) ; Beran, Vítězslav (advisor)
Bachelor's thesis is engaged in computer control with simple one hand gestures. There is described principal of hand detection by skin color recognition, processing and classification of hand gestures. The thesis includes implemented application for hand gesture recognition from video. For work with video library OpenCv is used.
Computer Game with Particle Systems
Vlková, Lenka ; Zemčík, Pavel (referee) ; Hradiš, Michal (advisor)
This bachelory thesis describes the design and the implementation of a 3D computer game with particle systems. The particle systems can be used for the simulation of a stochastic natural phenomena, for example fire and snow. In this thesis, you can find the description of the evolution of these systems, their uses and the description of the particular implementation. Other parts of the text are focused on another subjects involved in the game programming. The selection of an essential tool for game creation, a game engine, is crucial. Very important is also a collision detection that enables the movement of the objects in a game world and their responses to it. The design and the description of some parts of the implemented game is also a part of this work.     
Game with Body Movement Control
Crhák, Jaroslav ; Žák, Pavel (referee) ; Hradiš, Michal (advisor)
The work is dedicated to the processing of the human figures captured by the camera and its use for controlling computer games. There are given typical procedures for segmentation of images on the basis of movement and finding signs relating to binary image. Other part describes design of the application using informations about image.
Sky Detection in Images and Video
Vojáček, Cyril ; Hradiš, Michal (referee) ; Přibyl, Bronislav (advisor)
This work is about the sky detection in images and video. This paper describes the selected method of detection, which is used to create application. The focus is also on possible improvement the selected method. The result is an application, which is able to detect more types of sky. The work is mainly focused on the detection in image, but it is also possible to work with video. The correct detection is verified on the test set and the results of testing are presented in this paper.
Building deep networks using autoencoders
Lohniský, Michal ; Veselý, Karel (referee) ; Hradiš, Michal (advisor)
This thesis deals with pretraining deep networks by autoencoders. Components of neural networks are described in first chapters. Rest of chapters aims to deep network trainings and to results of experiments where autoencoder pretraining and Backpropagation algorithm are compared. Results showed positive contribution of autoencoder pretraining, mainly in combination with Finetuning.
