Segmentation of amyloid plaques in brains of trangenic rats based on microCT image data
Kačníková, Diana ; Kolář, Radim (oponent) ; Chmelík, Jiří (vedoucí práce)
The presence of amyloid plaques in the hippocampus highlights the incidence of Alzheimer’s disease. Manual segmentation of amyloid plaques is very time consuming and increases the time that can be used to monitor the distribution of amyloid plaques. Distribution carries significant information about disease progression and the impact of potential therapy. The automatic or semi-automatic segmentation method can lead to significant savings in the time which are required when the disease has rapid progression. The description of amyloid plaques and the computed tomography are included in this work. In this diploma thesis are three implemented algorithms, two of them are based on published articles and one’s own methodological solution. The conclusion of the thesis is a quantitative evaluation of the accuracy of implemented segmentation procedures.

Porovnání dat z chytrých telefonů, náramků a specializovaných zařízení
Kačníková, Diana ; Smital, Lukáš (oponent) ; Němcová, Andrea (vedoucí práce)
Táto bakalárska práca sa zaoberá porovnávaním dát z chytrých telefónov, náramkov a špecializovaných zariadení. V práci je zahrnutý popis možností záznamu pomocou rôznych zariadení ako je chytrý telefón, náramok Axivity AX3 a Fitbit Alta HR. Pomocou týchto zariadení boli nasnímané signály s rôznymi umiestneniami a vzorkovacími frekvenciami. Takto nasnímané signály sa implementovali na tri vytvorené algoritmy pre klasifikáciu aktivít. Pre každý signál sa vypočítala presnos[ detekcie a na základe týchto presností sa porovnali zariadenia, umiestnenia zariadení a vzorkovacie frekvencie. Stanovila sa ideálna kombinácia vzorkovacej frekvencie, umiestnenia a typu snímacieho zariadenia.

Comparison Of Data From Smartphones And
Specialised Devices
Kačníková, Diana
The aim of this study is to introduce two algorithms for physical activity recognition and to compare various devices such as smartphones and specialized devices using these algorithms. Signals are recorded using smartphones and accelerometer Axivity AX3. In the first part of the report, classification algorithms are described. In the second part algorithms are tested using recorded signals and the last part provides comparison of above mentioned tested devices.
