Generating Animations with Neural Networks
Dráber, Filip ; Kohút, Jan (referee) ; Hradiš, Michal (advisor)
Ačkoli je snímání pohybu už tak nástrojem, který má animátorům pomoci zjednodušit ty nejsložitější aspekty tvorby realistických animací, spousta námahy je stále ukrytá v anotování a strukturalizaci těchto dat. Tento problém řeším návrhem neuronové sítě, která může být natrénována na datovém souboru nasnímaného pohybu tak, aby reprodukovala lidský pohyb, který je vizualizován v aplikaci, které umožňuje uživateli tento pohyb ovládat. Také experimentuji s různými metodami trénování autoregresivního modelu, a na základě toho určuji, která metoda nejlépe vyvažuje dobu trénování a výkon. Dalším postřehem je, jak přidání ovládacích hodnot do vlastností generovaných snímků ovlivňuje použití rekurentních neuronových sítí pro tento úkol.

Advanced Character Animation
Matýšek, Michal ; Polok, Lukáš (referee) ; Kajan, Rudolf (advisor)
This thesis describes modern real-time character animation techniques and their implementation in C++ language using DirectX and PhysX libraries. The first part of the text deals with a presentation of selected animation principles and is focused mailny on key-frame animation, skeletal animation, morphing and ragdoll simulation. Then follows a description of used DirectX and PhysX libraries and description of motion capturing, using iPi Desktop Motion Capture software. The second part of this thesis is focused on particular ways of implementation of the described animation techniques.

Judgement of personality based on recordings of dance and gait (obtained using Motion Capture)
Vávra, Jan ; Lindová, Jitka (advisor) ; Krejčová, Lucie (referee)
Judgement of personality based on recordings of dance and gait (obtained using Motion Capture) This study raises the question if it is possible to assess personality traits based on body movement while dancing and walking if we isolate movement from other non-verbal cues. The theoretical part of the study lists theoretical concepts associated with this question and summarizes previous research on the subject. The main part of this study is empirical research: the movement of 21 women was filmed using Motion Capture technology which captures human movement by recording the coordinates of key segments of the body. A virtual female character was used to re-create the movement of the research participants. The resulting footage was then presented to 187 raters, who scored segments of it on two sets of personality scales. The comparison of the raters' scores and self-assesed personality of the participant is subject to the analytical part of this study. The results showed several correlations between assesments of personality traits and self-assesed personality traits, but those were never the same traits (i. e. extraversion was never recognized as extraversion, but possibly manifested itself thorugh ratings of other traits). We also found several more general factors on which the raters' assessments of...

Kinect - utilising in the occupational therapy
Nushartová, Marie ; Oborná, Pavlína (advisor) ; Čábelková, Alžběta (referee)
The theme of this thesis is the use of Kinect in training of movements which are used in Activities of Daily Living (ADL) of patients with brain damage. Teoretical introduction is dedicated to analysing possible neurophysiological mechanisms which could be applied in rehabilitation with using of Kinect such as biofeedback, repetitive movements, complex paterns of movements. Training response was tested on the pilote sample of two patients: one with right-handed spastic hemiparesis after hemorragic stroke, the other with kvadruparesis, disability of low to medium-size of both superior limbs, more severe right, after craniocerebral trauma with multiple contuses of brain. Training was applied in series of six training days during several weeks. Development of results was expressed quantitatively using arithmetic averages achieved in particular days and variability was expressed by value their average absolute deviation. To compare development of training achievements and development of abilities fine and gross motor skills of patients was used Jebsen - Taylor Test. In the thesis are discused appropriate attributes of virtual reality to utilise in the occupational therapy and also possible problems and contraindication of some diagnoses simultaneously. Key words: Kinect, Motion capture, virtual...

Correlation of personality traits with gait and dance movement using data produced by Motion Capture technology.
Rynešová, Magdalena ; Lindová, Jitka (advisor) ; Bečev, Ondřej (referee)
ABSTRACT. This research is following Ecological Theory about the ability of humans to form impressions from observing the behavior of other people. The current study examined whether personality traits were related to the way in which people walked and moved to certain music. Twenty-one young females were asked to walk and to move to slow and fast music and to dance with a partner. Their movements were tracked with a MOCAP system which can produce coordinates of points on a moving body. A number of different measurements of body movement were produced and analyzed. Participants also completed the Big Five personality inventory. A number of trends were found in relationships between personality traits and gait and dance movement. Extroversion had the biggest influence. It was related to bigger and faster movements, especially with movements of head, hands, shoulders, hips or footstep. Openness to experience tended to have similar influence as extroversion. Neuroticism influenced slow dance the most. Agreeableness and conscientiousness had both positive and negative influence to a lesser extent. They influenced especially movements of hands, hips or footstep.

Leg prothesis
Bulva, Ondřej ; Harabiš, Vratislav (referee) ; Balogh, Jaroslav (advisor)
This thesis deals with the current state of development of active lower limb prostheses and focuses mainly on own design of active prostheses. The introduction deals with the anatomy of lower limb and briefly describes the walk cycle. In other chapters are summarized amputation techniques in the lower limb, followed by a description of the allocation of prostheses according to the level of amputation, which were described in earlier chapters. The thesis also deals with the division of prostheses according to the patient's activity level and briefly describes the structural differences in these individual cases. Chapter describing the actual development in the field of active prostheses initiates part dealing with the detailed description of the part of the prosthesis. The following chapters deal with the design and implementation of a prototype of active transfemoral prosthesis. The penultimate chapter deals with the software description of all parts of the prosthesis. This chapter is followed by an evaluation of the achieved results.

3D Reconstruction of Human Body Motion (MOCAP)
Černák, František ; Svoboda, Pavel (referee) ; Šolony, Marek (advisor)
This thesis deals with object recognition in image, motion capturing and his transformation into 3D coordination system and 3D reconstruction. The problem was solved by building stereo camera system, detection of markers on a moving object and getting his position in space using triangulation. Hit rate of 95% was achieved in marker detection at close range and accuracy of 3D reconstruction answers to reality at certain extend. The main finding of this work is that it is possible to reconstruct body motions with a pair of simple web cameras.

Movement Identification in the Space
Šolony, Marek ; Beran, Vítězslav (referee) ; Potúček, Igor (advisor)
The aim of this paper is to suggest optical system capable of movement identification in space and its reconstruction. The motion capture system uses markers attached to parts of human body, and a camera pair to capture the movement. This paper describes step-by-step parts of this system. Epipolar geometry is used to deal with problem of object correspondence between two views.
