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.

Comparative analysis of pelvic girdle muscles and body muscles activation during walking in different types of shoes and barefoot
Hrůzová, Zuzana ; Bačáková, Radka (advisor) ; Pánek, David (referee)
Title: Comparative analysis of pelvic girdle muscles and body muscles activation during walking in different types of shoes and barefoot Objectives: The aim of this thesis is to compare EMG signal chosen muscles of pelvis girdle and trunk while walking barefoot, shod in barefoot shoes or in conventional sport shoes. Methods: In our research there were 9 healthy participants who are used to walking in barefoot shoes attending. Using surface electrodes, the EMG activity of 5 muscles was recorded. The observed movement was walking on grass in conventional shoes, in barefoot shoes and barefoot. The data obtained from the experiment were imported and statistically processed in the MS Excel program with the XLSTAT software installed and in the Jamovi statistical program. ANOVA and unpaired t- test were used for statistical data analysis. Results: Data from the statistical comparison revealed a significant statistical difference in 75 % comparison of maximal muscle activity between walking in conventional sport shoes, barefoot shoes and barefoot in measurement of differences in one subject in all chosen muscles. A statistical significant difference was also found in comparison of maximal muscle activity in 81,43 % measurements between subjects in all chosen muscles while walking barefoot. There was no...

Phylogenetical consequenses of human locomotion realizated during the schoulder girdle
Ryšánková, Lenka ; Kračmar, Bronislav (advisor) ; Véle, František (referee)
Title: Phylogenetical consequenses of human locomotion realizated during the schoulder girdle Objectives: Description of phylogenetic context of human locomotion realized through the shoulder girdle Methods: Study and analysis of the available literature Analytic-synthetic comparison of the current knowledge of evolution Study of available sources of phylogeny of locomotion in terrestrial vertebrates Results: It was found similarity in the basic control of human bipedal locomotion to control of quadrupedal locomotion of other animals and similarity in the specific form of human locomotion to locomotion of non-human primates Keywords: Bipedal locomotion, quadrupedal locomotion, control of locomotion, interlimb coordination

Nordic Walking - muscle response at movement apparatus in pelvis area
Hrouzová, Lenka ; Kračmar, Bronislav (advisor) ; Satrapová, Lenka (referee)
Title: Nordic walking - muscle response at movement apparatus in pelvis area. Purposes: The aim of the thesis is to compare muscle timing in pelvis area using EMG during free bipedal walk and during the walk with special sticks. Methods: Surface electromyography combinated with kinematografy analysis used synchronized video recording. Results: It Managed to prove different muscle timing at nordic walking and at free walk. It was proved lower activity of stabilization muscles at walk with sticks. Key words: Nordic walking, surface electromyography, stabilization muscles, kinematics analysis, bipedal locomotion
