Face recognition and emotional expression processing in primates
Englerová, Kateřina ; Nekovářová, Tereza (advisor) ; Fajnerová, Iveta (referee)
Visual modality is one of the most important senses for primates and also for many other an-imals. It allows them to perceive stimuli from their environment - important objects and places, and also conspecifics or individuals of other species. One of the crucial cognitive skills, especially for social animals, is the ability to distinguish between individuals and their emotions due to different facial features and expressions.Aim of this work is to summarize the current knowledge about face and emotion recognition. It includes neurological mechanisms, experimental methodologies and comparison between species.

Fast Detection of Natural Objects
Zelinka, Martin ; Bartl, Vojtěch (referee) ; Šimon, Martin (advisor)
Thesis deals with the detection and localization of dogs in the image. It analyzes computer vision techniques suitable for solving this problem. It is designed and then implemented solution. Data set of images representing the object of the search and the data set of negative images are created. The resulting solution is finally subjected to training in order to determine the best parameters for used algorithms. The resulting program is included in the attached DVD.

Tracking and Recognition of People in Video
Šajboch, Antonín ; Hradiš, Michal (referee) ; Smrž, Pavel (advisor)
The master's thesis deals with detecting and tracking people in the video. To get optimal recognition was used convolution neural network, which extracts vector features from the enclosed frame the face. The extracted vector is further classified. Recognition process must take place in a real time and also with respect are selected optimal methods. There is a new dataset faces, which was obtained from a video record at the faculty area. Videos and dataset were used for experiments to verify the accuracy of the created system. The recognition accuracy is about 85% . The proposed system can be used, for example, to register people, counting passages or to report the occurrence of an unknown person in a building.

Speed of learning multilayer network
Maceček, Aleš ; Zámečník, Dušan (referee) ; Jirsík, Václav (advisor)
Theoretical study about neural networks, especially their types of topologies and networks learning. Special attention is attended to multilayer neural network with learning backpropagation. Introduced learning algorithm backpropagation of simple networks in conjunction with descriptions of parameters affecting network learning also methods to exaluation quality of network learning. Definition moment invariants to rotation, translation and scaling. Optimalization parameters of neural networks to find the network which has the fastest learning and also the networks with the best value of recognition patterns of letters from testing set.

Braille Reader
Fabík, Jiří ; Svoboda, Pavel (referee) ; Maršík, Lukáš (advisor)
This thesis deals with image processing, specifically scanned Braille documents. It is about recognition of Braille cells, followed by transferring to plain text. Braille dots are recognized on the basis of bright and dark parts, which are created during scanning. After connection to the characters, they are converted to plain text by means of the character set. It also locates positions of possible errors to make it easier to correct the final text.

Image Object Rcognition Using Android Platform
Šimon, Martin ; Zahrádka, Jiří (referee) ; Zemčík, Pavel (advisor)
This thesis describes an object recognition issue in connection with the Android mobile platform. It analyzes existing methods and procedures from the field of the object recognition as well as previous solutions of a similar topic. It builds on these basics and proposes a handy application which aspires to become a powerful assistant during mushroom picking. It considers the target device, which is memory and power limited, during the design and implementation phase. The results are evaluated by several experiments including an user experience. The implementation of the application itself is a part of this thesis.

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.
