Algorithm for Realistic Vascular Circulation of Synthetic Retina
Dvořák, Martin ; Drahanský, Martin (referee) ; Semerád, Lukáš (advisor)
The aim of this bachelor thesis is to improve an existing tool for creating synthetic retina of the eye. The improvement of an existing software is carried out by changing the algorithm for creation vascular bed. The problem was solved by designing an algorithm which is based on real behavior of vascular system in the retina of the eye. Real pictures were statistically recorded. Mathematical programs created aproximation curves of the blood vessels. Directions of the blood vessels, locations of branching and a number of branching of blood vessels were observed. A model for generation of synthetic pictures was designed based on discovered information and probability of branching. The main results are synthetic retinas which contain patterns of behavior of a real retina of the eye. These pictures have similar number of blood vessels, aiming towards the same location and branching in the same points as real pictures.

Generation of Synthetic Images of Eye Retinas
Tretter, Zdeněk ; Maruniak, Lukáš (referee) ; Drahanský, Martin (advisor)
The goal of this thesis is to design and implement a program capable of automatically generating synthetic images of eye retinas. The generated images should be similar to those of real retinas, which are hard to obtain, so they could be used for development of various algorithms, which work with eye retina images in their place. This thesis describes anatomic properties of the eye retina, ways to take images of it and also usage of eye retina recognition in biometric and medicinal applications. Design of the program and the way in which individual parts of the retina are assembled together into the final image is also explained in this thesis. These individual parts are created using procedural textures in separate layers of the image. Next chapter of this work describes implementation details of the program. The conclusion then experimentally verifies suitability of the generated images for algorithmic processing.

Automatic Producing of Cranial Implant Edge Surface
Hrdý, Libor ; Bartoň, Radek (referee) ; Kršek, Přemysl (advisor)
This thesis is focused to problems of automatic generation of border surface for cranial implant. This document includes description of 3D modeling human tissue, followed with issue of cranial implant. Next it includes possible perspectives of solving automatic generation problems for implant border. Second half of this document is focused to implementation of tool for automatic generation of border surface. Final part deals with results of work with this tool.
