Creating a Depth Map of Eye Iris in Visible Spectrum
Kubíček, Martin ; Kanich, Ondřej (oponent) ; Drahanský, Martin (vedoucí práce)
The aim of the master thesis is to propose and introduce in practice the methodology of scanning the iris of an eye in the visible spectrum. It emphasizes the quality of images, credible color rendering in comparison to the real basis and, in particular, the continuous depth of sharpness that could reveal previously unexamined aspects and details of the iris. Last but not least, the thesis will also focus on minimizing exposure to physical stress tot he iris. Part of the methodology is a precise procedure for iris imaging while ensuring image consistency. This will allow the creation of an iris database that tracks their evolution in time or other aspects such as the psychological state of the person being scanned. To start with in practice, the anatomy of the human eye and especially that of the iris is presented. Known methods of iris scanning are given. Then, there is a section about proper iris lighting. This is necessary for the desired level of image quality but at the same time it exposes the eye to great physical stress. It is therefore necessary to find a compromise between these factors. Important is the very description of the methodology itself as it describes in detail the scan. Furthermore, the thesis deals with necessary post-production adjustments, such as compiling images with different depths of sharpness into a single continuous image or applying filters to remove defects from the images. The last part of the thesis is divided into evaluation of the results and the conclusion in which is discussed the possible extension or modification of the methodology so that it can be used outside the laboratory conditions.
