Methods for flow estimation using laser speckle contrast imaging
Jahůdková, Michaela ; Harabiš, Vratislav (referee) ; Kolář, Radim (advisor)
This thesis deals with introduction to optical method called laser speckle contrast imaging (LSCI). The thesis contains a description of the basic theory that is related to the method, the LSCI own principle, the characteristics of this technique, its applications and also a description of various variants of LSCI. The second part of the thesis deals with the modification of acquisition software to be suitable for measurement of multi-exposure LSCI (MESI), verification of this method by experiment and conclusions of evaluated of data.
Blood-vessels segmentation in 3D volume data from optical coherence tomography
Jahůdková, Michaela ; Štohanzlová, Petra (referee) ; Kolář, Radim (advisor)
This thesis deals with introduction to the optical coherence tomography and blood-vessels segmentation methods in 3D volume data optical coherence tomography. The thesis also includes a description of the anatomy of the eye and physiology of the visual perception. The end of the thesis includes the design and implementation of a method of segmentation of blood-vessels in the volume data on real data and discussion of results.
