Liveness Detection of a Hand
Vanický, Jozef ; Kanich, Ondřej (referee) ; Sakin, Martin (advisor)
This thesis solves the security problem of biometric systems which uses biometric data of a hand. It focuses on the absence of liveness detection during verification of a sample by the biometric system. In result this thesis offers to extend the contactless biometric systems by a system of liveness detection, which utilizes specific properties of human skin and its reactions to certain wavelengths of the visible spectrum of electromagnetic radiation. Reactions of the skin on the specific wavelengths of visible spectrum are analyzed and compared with the reactions of inorganic materials which imitates the hand. Outcome of this thesis is a design and implementation of a liveness detection algorithm, which can, based on the analysis of a set of photographs of the human palm, which was exposed to four wavelengths of a visible part of the electromagnetic spectrum, successfully recognize a hand from a counterfeit with an average accuracy rate of 82.20 %.

Depth-Based Determination of a 3D Hand Position
Ondris, Ladislav ; Tinka, Jan (referee) ; Drahanský, Martin (advisor)
Cílem této práce je určení kostry ruky z hloubkového obrazu a jeho následné využití k rozpoznání statického gesta. Na vstupu je hloubkový obrázek, ve kterém je nejprve detekována ruka pomocí neuronové sítě Tiny YOLOv3. Následně je obrázek zbaven pozadí a z takto předzpracovaného obrázku je určena kostra ruky v podobě 21 klíčových bodů neuronovou sítí JGR-P2O. K rozpoznání gesta z klíčových bodů ruky byla navržena technika, která porovná kostru na vstupu s uživatelem definovanými gesty. Funkcionalita systému byla otestována na vytvořeném datasetu s více než čtyřmi tisíci obrázky.

Design and Control of a Hand Prosthesis
Žajdlík, Jakub ; Skalický, Jiří (advisor)
Práce předkládá metody a výsledky návrhu, výroby a výzkumu pětiprsté protézy ruky. Inspirace jdoucí z přírody a z toho vyvozený princip použitého mechanizmu je uveden. Základní koncept řídícího schéma založeného na procesingu a ohodnocení EMG je navrhnut a implementován. Části senzorického systému protézy jsou navrhnuty a zahrnuty do rídícího algoritmu a shématu. Velké množství inovací a návrhů pro budoucí práce a výzkum jsou prezentovány, stejně tak komplexní analýza a diskuse dosažených a možných budoucích výsledků.

Detection, Extraction and Measurement of the Length of the Metacarpal Bones in X-Rays of the Human Hand
Chalupnik, Alexandr ; Rydlo, Štěpán (referee) ; Drahanský, Martin (advisor)
The aim of the bachelor thesis is the design and implementation of an algorithm for the detection, extraction and measurement of the length of the metacarpal bones in x-rays of the human hand. The first part is focused on the principles of x-rays and the anatomy of the human hand. The second part contains the design and implementation of the task. The algorithm is based on image processing methods, such as thresholding or edge detection. In the end, the measurement results are evaluated on a set of images, which were provided by the Department of Anthropology at Masaryk University.

Hand Motion Recognition
Blaho, Juraj ; Beran, Vítězslav (referee) ; Hradiš, Michal (advisor)
The aim of this work is to design and implement a novel computer interface based on detection and tracking of a hand in an image from a single camera. The created interface doesn't require any special hardware and it is possible to use it on a common computer with standard web-camera. The implemented interface was used to create an application, which is able to synthesize keyboard and mouse input events and this way it is able to control existing programs without the need to change their source code. Another contribution of this work is a novel method of automatic data acquisition for training of hand detectors. By using this method it is possible to collect thousands of training examples in a few hours.

Robotic Hand with RC Model Servos
Doležal, Filip ; Musil, Petr (referee) ; Zemčík, Pavel (advisor)
The thesis deals with the design and creation of a robotic hand using standard RC servomotors, ways of its control and subsequent creation of a program designed for its control. It attempts to solve the most suitable ways of controlling the servomotors, especially with regard to their finest operation.

Electical stimulation of hand muscles
Hrozáň, Michal ; Balogh, Jaroslav (referee) ; Sekora, Jiří (advisor)
Bachelor thesis explains the effect of electrical stimulation on muscle and nerve fiber. It describes the process of stimulation and principles that apply while stimulation with electric current is applied. Specific muscle stimulation of thumb is described. Work provides a solid base of knowledge for understanding the processes that are present in stimulation of living tissue, which will be implemented in construction of stimulator. User graphical interface was created in Matlab. User can communicate using this program with microcontroller ATMega328 of Arduino Uno Board. Microcontroller processes received data and generates voltage on its output pins. An amplifier and electrode triggering system was designed as well.

Occupational therapy in the rehabilitation of patients after fracture of the distal radius and hand
Malečková, Zuzana ; Nováková, Petra (advisor) ; Nováková, Olga (referee)
BACHELOR THESIS ABSTRACT Name, Surname: Zuzana Malečková Supervisor: Mgr. Petra Novotná Consultant: Bc. Aneta Křivánková Title: Occupational therapy in the rehabilitation of patients after fracture of the distal radius and hand Abstract: This is a theoretical-practical work. The theoretical part briefly describes the anatomy and kinesiology of the upper limb with a focus on the hand and wrist, and then presents a summary of the most common fractures in this body part. The last and the longest chapter is about the possibilities of occupational therapy for patients fractures of the distal radius and hand, especially in the period after removal of fixation. Occupational therapy has a very wide application for these patients. Functional disorders of the hand and wrist, which are a frequent complication of fracture treatment, are often closely related to the limitation of self-sufficiency and have a great impact on the patient's quality of life. The aim of the practical part is chosen and verify the occupational therapy methods for people with fractures of the distal radius and hand. This section contains case reports of three patients, two of whom suffered a distal radius fracture and one with fracture of the fifth metacarpal. Each case report contains a detailed initial and discharge examination with a focus...

Rehabilitation after combinated tendon and nerve injury of the hand
ŽÁKOVÁ, Kateřina
This bachelor thesis aims to clarify the adequate rehabilitation procedures after lesions of the tendon and nerve apparatus of the hand, which were applied to the patient with a hand injury. The benefit of the selected rehabilitation methods was subsequently commented on in the discussion. The theoretical part deals with the anatomy and physiology of the hand, concretely with the flexor and nervous apparatus, which is essential for establishing the rehabilitation processes and improving collaboration between attending physicians. For a better orientation and understanding of the postoperative care, the thesis describes the procedures related to the surgical treatment of flexor tendons and nerves injury. It further introduces the most common rehabilitation procedures, soft tissue, antiedema and physical therapy, desensitization exercises, and adhesion prevention. Lastly, I comment on the protective splinting for the hand after tendon lesions and selection of splinting materials. In my bachelor thesis I applied qualitative research method. A patient from the Institute of Hand Surgery and Plastic Surgery in Vysoké nad Jizerou with a tendon and nerve lesion after trauma participated in the research. After the operation, a rehabilitation plan was created, applied and observed. The patient's condition was monitored from the day of the surgery for six months. Each checkup I cooperated with the surgeon.
