Detection of delay between arterial and venous pulse signal from videoophthalmoscope
Pejskar, Michael ; Mézl, Martin (referee) ; Valterová, Eva (advisor)
The goal of this bachelor´s work is to measure a time difference between arterial and venous pulses on a retina from video sequences obtained from a binocular videoopthalmoscope. Theoretical part contains a description of the eye and its structures, description of the imaging devices used to display ocular background and research of methods used to measure and calculate the delay between pulses. Practical part describes the processing and adjustments of the videosequences and the measurement of time differences using foot-to-foot and phase difference method.

Analysis of pulsations in retinal image data
Plavcová, Daniela ; Kolář, Radim (referee) ; Odstrčilík, Jan (advisor)
Analysis of pulsation in retinal image data can be used to early diagnose of glaucoma. With the record of experimental videoophthalmocope and subsequent segmentation of optic disc the pulsation curves from various parts of optic disc were evaluated and the dependence between brightness, PAA and RNFL parameters was compared.

Plethysmography for retinal video processing
Plavcová, Daniela ; Valterová, Eva (referee) ; Kolář, Radim (advisor)
Sight is one of the five human senses and is very important for exploring near and far surroundings. However, this is prevented by various eye defects, which may be related to the vascular system of the retina and the pulsations that are observable on it. This work deals with the study of the relationship between the mentioned pulsations and glaucoma. To search for connections between these two aspects, video recordings from the retina are used, the pulsation of which is further worked in the form of a 1D signal, especially in the spectral region.
