Automatic delineation of ECG signals
Žiak, Milan ; Smital, Lukáš (oponent) ; Vítek, Martin (vedoucí práce)
This thesis deals about automatic delineation of ECG. We use algorithm, which is descriped by autors Lagune, Jané and Caminale. Their work uses first derivation for delineation ECG signal. This bachelor thesis also uses a wavelet transform to reach better results.

Spatial registration of partially overlapping retinal images
Žiak, Milan ; Harabiš, Vratislav (oponent) ; Valterová, Eva (vedoucí práce)
Adaptive optics give us opportunity to capture high resolution images of retina, even we are able to detect cones. Spatial registration of retina images has to be done due to scanning process of capturing, because current opthalmoscops with adaptive optics aren't able to capture whole area of retina. Diploma thesis demonstrates basic princip of automatic spatial registration of overlaping images. It uses constellation features for matching some of the detected cones. K-means combinate wiht RANSAC is used for outlier detection. Inliers matching pairs are then used to define a affine transformation matrix. This method was aplied on dataset retina images from AO-FIO modality and evaluation of quality was computed according to normalized mutual information. Result shows that this metod is suitable for registration AO-FIO images with "cell-to-cell" accuracy.
