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.

The Upper Limb Prosthesis And Its Impact On A Patient's Mental State
Štechová, Eva ; Bachura,, Marek (referee) ; Zdařil, Zdeněk (advisor)
Bachelor's thesis deals with myoelectric upper limb prosthesis and it's effect on mental state of the patient. It was created as a collaboration with company OTTOBOCK SLOVAKIA s.r.o, company that distributes prostheses and other devices to help improve or preserve mobility for disabled patients. I chose one of their products, Greifer, and decided to do a redesign. Greifer is a prosthesis made for delicate work with small objects on one hand, on the other for harder work that requires a firm grip. I created the design with regards to ergonomics, functionality and aesthetic quality. My aim was to create a product that a patient would easily get used to, and it would not draw negative attention of other people, which would have negative effect on a mental health of the patient. Functionally I followed the today's Greifer system provided by Ottobock at first, but then I added the function of rotation around spherical joint, inspired by an actual human wrist joint.

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...

Device/Robot Exploiting RC Components and Servos
Němec, Daniel ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The thesis deals with the design and creation of a robotic manipulator using RC servomotors, control options and the subsequent creation of a control web application. It also deals with the kinematics of the robot for it's control and smoothing of the servomotors motion. The result is robotic arm controlled with web application.

Liveness Detection of Human Hand from Multispectral Images
Lebedeva, Polina ; Malaník, Petr (referee) ; Sakin, Martin (advisor)
This bachelor thesis focuses on the detection of the liveness of a human hand from multispectral images. The main objective is to design and implement an algorithm for recognizing live hands and spoofs based on the analysis of hand images illuminated by specific wavelengths. The work describes various techniques for extracting important features from images, their processing, and methods for determining liveness
