Person Identification Based on Locomotion
Pražák, Ondřej ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
This paper deals with study of human movement and using that in identification. In the first part of my work are explained characteristics of human movement and factors which take effect on these characteristics. Practical part is dealing with design of program which is solving mentioned problems. The input of program is created by video sequence with lateral movement of human. The program is finding coordinates of lower limbs joints. From this coordinates are created locomotion characteristics used for human identification. Matching of time behaviors is based on correlation.

Motion Analysis
Hudec, Jiří ; Čmiel, Vratislav (referee) ; Sekora, Jiří (advisor)
Bachelor thesis is dealing with how to analyze human walk with Vicon camera system. In the first chapter are described elementary ideas for gait analysis and principal methods of Vicon system. There is also discussed basic layout of cameras in the laboratory and layout of markers attached at a human body. The second chapter is also about synchronisation of multiple cameras and description of CVS format. Further, in the third chapter are discussed four algorithms created in Matlab for a description of gait analysis. In the last fourth chapter are discussed the results of the software from Matlab and comparison these results with results made in the laboratory of gait analysis.

Person's identification by means of bipedal locomotion
Krzyžanek, Jakub ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The aim of this thesis is to recognize a walking person in a sequence of images by defining his or her reference points to compare the course of their movement and then to identify the scanned person. Methods „k-means“ and „mean shift“ are used to obtain the silhouette of the person. However “environment model estimation” method is used here before those mentioned above. It is a type of a difference method and it helps to specify the scanning area and shortens the time of segmentation. During the search for the reference points the thesis focuses on three areas: the centre of the head and both ankle joints. Those points are later determined on the previous image sequence and compared with the real locations of the centre of the head and ankle joints marked by the user. The thesis also focuses on comparing the movement courses of those points and tries to identify the people whose walks are being scanned. Problematic situations which occurred during the whole process are analyzed in the end. The result of the thesis is an algorithm which can locate a moving person in an image sequence (video) and determine the reference points (centre of the head and ankles) to compare them and identify the scanned person.

Kinetic analysis of signals from gait laboratory.
Benešovská, Veronika ; Mézl, Martin (referee) ; Svozilová, Veronika (advisor)
Gait analysis has an irreplaceable meaning in many various fields. Thanks to the Vicon system, which is used in gait laboratory, the movement of individual body parts can be captured. The purpose of this work is to process data records from gait laboratory, and kinetic analysis in Matlab program. The main target of the bachelor thesis is to compare detected values, which were evaluated by kinetic analysis of the data obtained from tested subject during performing the exercise and creating GUI.

Motion Analysis
Hudec, Jiří ; Čmiel, Vratislav (referee) ; Sekora, Jiří (advisor)
The thesis describes the optical camera system from Vicon, which records human movement. In medicine, this technology is used in laboratories for walk analysis. In collaboration with the laboratory in the Brno Faculty Hospital, two sets of anonymised patient results are analyzed by designed algorithms in Matlab. Algorithms were design for processing data in 2D and 3D views and to display kinematic joint analysis. The practical part evaluates the functionality of the proposed algorithms and compares them with results from the laboratory.

Walking as alternative source of electrical energy
Smilek, Jan ; Hejč, Tomáš (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with problematics of using the Energy Harvesting principles for generating power from the human walking. Own acceleration measurement during walking was made on various locations of human body to provide data for self-developed MATLAB/Simulink energy balance script. The script clearly sets the possibilities and limits of vibration generator used in this application. Conclusions of the energy balance were used to specify requirements for development of vibration generator and few possible conceptions, working on frequencies close to 2 Hz and acceleration amplitudes 0,3 g, were presented, or simulated.

Implementaion of the controllers of a mobile walking robot
Krajíček, Lukáš ; Věchet, Stanislav (referee) ; Ondroušek, Vít (advisor)
This diploma thesis deals with design and implementation of the controllers of a mobile walking robot. The advantage of these controllers are their kinematics and geometrics independent representation, which allow to use them for different robot types and tasks. In this thesis the contact controller is designed, which minimizes residual forces and torques at the robot's center of gravity, and thereby stabilize robot's body. Next the thesis deals with a posture controller, which maximizes a heuristic posture measure to optimize posture of robot body. Because of this optimization, legs are moved away from their limits and therefore they have more working space for next move. Implementation of the chosen solution is made on the robot's MATLAB mathematical model. Controllers are composed into a control basis, that allows to solve general control tasks by simultaneous combination of contained controllers. The algorithm was created for that simultaneous activation and its operation was explained on flow charts.

Dynamic plantography
Grossmann, David ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
This thesis contains introduction to the principles of dynamic plantography and it´s clinical application. Afterwards it is described feet anatomy, types of feet arch and human walking process. Next part describes principles of various types of tactile sensors and electrical platform Arduino. Most important part of this thesis is focused on teoretical design of device and it’s practical realization. The last part of diploma thesis is devoted to discussion of parameters of the device and to results of measuring of group of volunteers.

Design of lower-limb prostheses
Koutecký, Tomáš ; Ždímal, Pavel (referee) ; Paloušek, David (advisor)
The goal of this bachelor's thesis is to give an overview of the current state of lower limb prostheses after amputation between the hip and the knee. It deals with the human gait, its analysis and with deviations in gait with the prosthesis. It also describes basic division of lower limb prostheses. The main part is the description of these prostheses designs and especially the design of main components and general overview of available types.

Design of the vacuum treadmill
Havránek, Jakub ; Chorý, Tomáš (referee) ; Křenek, Ladislav (advisor)
The diploma thesis concerns with the design of the vac- uum treadmill. The aim was to create a vision of this machine for the near future. As the final result we en- counter a brand new conception, consisting of the outer stable base, inner tilting base, upper frame with steel handle, control panel and airtight bellows. The design includes 3 different colour schemes. The first part of the thesis analyses the historical de- velopment and construction and design solutions. The second part describes this particular design project in detail, including its development.
