Windows Phone 7 Application for Traffic Sign Recognition
Dvořák, Marek ; Orság, Filip (referee) ; Procházka, Boris (advisor)
Purpose of this thesis is to create an application that detects and recognizes traffic signs for mobile phones running Windows Phone 7 operating system. Theoretical part contains information about history and characteristics of Windows Phone 7 system, traffic signs in Czech Republic and various methods of image processing. Practical part of this thesis describes particular implementation of recognizing of traffic signs in photographs taken with mobile phone built-in camera. In last part this app is tested in real-life conditions and results of these tests are evaluated.

Detection and recognition of speed limit road signs
Solnický, Vojtěch ; Krejsa, Jiří (referee) ; Grepl, Robert (advisor)
This master‘s thesis describes the design and implementation of the system for detection and recognition of speed limit road signs. It focuses on the recognition of the red circular speed limit sign from the image data using the computer vision methods. Several methods were programmed and tested as a part of this thesis. In the final solution, the segmentation based on YCbCr color model is used. Detection of the circular sign and final classification is performed by template matching method. Algorithm for the tracking of the detected signs between frames of the video is used for better performance in real-time recognition. Application is developed using MATLAB and Simulink. The result is a simple driver assistance system prototype, which can be implemented in any computer with camera. The correct function of the algorithm was confirmed during a testing in a traffic.

Detection, Localization and Recognition of Traffic Signs
Svoboda, Tomáš ; Juránek, Roman (referee) ; Herout, Adam (advisor)
This master's thesis deals with the localization, detection and recognition of traffic signs. The possibilities of selection of areas with possible traffic signs occurrence are analysed. The properties of different kinds of features used for traffic signs recognition are described next. It focuses on the features based on histogram of oriented gradients. Some possible classifiers are discussed, in the first place the cascade of support vector machines, which are used in resulting system. A description of the system implementation and data sets for 5 types of traffic signs is part of this thesis. Many experiments were accomplished with created system. The results of the experiments are very good. New datasets were acquired from approximately 9 hours of processed video sequences. There are about 13 500 images in these datasets.

Traffic sign detection in real time
Sicha, Marek ; Přinosil, Jiří (referee) ; Bravenec, Tomáš (advisor)
The bachelor's thesis focuses on the detection and classification of traffic signs in images and video sequences. The goal of the work is also the possibility to perform detection and classification on a single board computer. Neural networks and the Python programming language were chosen to solve the problem. Object detection and classification are solved separately, so two neural networks were used. A convolutional neural network was chosen for classification and a detector from the EfficientDet family was chosen for detection. The overall architecture was tested on a single board Nvidia Jetson Nano computer.
