Analysis of retinal vessel pulsation
Holásková, Anna ; Mézl, Martin (referee) ; Odstrčilík, Jan (advisor)
The content of this work is the analysis of retinal vessels pulsation of video sequences acquired by experimental fundus camera based on measuring the brightness profile of the vessel. The first level of analysis in this work is the segmentation of blood vessels and diameter measurement of blood vessels during the sequence. The work contains research methods dealing with the diameter measurement and evaluation of pulsation and analysis segmentation methods using for analysing the vasculature of the retina. From these methods, a vessel tracking method was selected. In segmented video sequences is on the ground of intensity profiles analysed vessel pulsation. Analysis is also made on original dataset and results are discussed considering the frequency characteristic.

Analysis of temporal retinal sequences
Nováková, Marie ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This thesis deals with a method of the retinal image acquisition by fundus camera, their properties and evaluation of the retinal vessel diameter from acquired images. Several studies dealing with usage of retinal vessels diameters for hypertension, cardiovascular diseases, diabetes mellitus and glaucoma are described. The second part of this thesis is focused on the extraction of the retinal blood-vessels pulsation from retinal sequences and the basic processing of extracted pulsation signals. The proposed method is described in details and tested on one dataset.
