Internet library of methods and algorithms used for medical image registration
Koňařík, Jakub ; Fedra, Petr (referee) ; Peter, Roman (advisor)
Image registration is a procedure which is heading to search for a geometric transformation, which ensures same position, orientation and size of coresponding objects in pictures. How does these methods work? These methods and principies are explained in first part of this work. Second part of this work is aimed to explain theory about information systems and practical creation of the internet databaze. These practical part was realized in editorial system called Drupal.

Temporal interpolation of ophthalmologic video sequencies using multimodal registration
Kadla, Jan ; Odstrčilík, Jan (referee) ; Jan, Jiří (advisor)
This master’s thesis gives a description of fundus camera as a medical imaging system. Sub features of this system are explained in short, thus examples of certain construction variants are given. Furthermore, the work deals with image fusion and associated possibilities of digital image processing. One set of consecutive scanned images of human eye’s retina has been provided for the practical part of this work. During program processing of these data, decomposition of obtained images to single-color sequences is performed. For these partial monochromatic sequences, monomodal registration is performed, based on calculation of the brightness similarity criterion between the pairs of images. From the three created monochromatic sequences of registered images, new sequence of color images is created, using multimodal registration of each image triples. As a basis for similarity evaluation during multimodal registration, an information similarity criterion was used.

Registration of Ultrasound Image sequences
Kubica, Roman ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
The result of this thesis, focused on medical image registration, is an automatic image registration algorithm. It is constructed to be used on real ultrasonography images, created by perfusion imaging. In its introductory part, the thesis deals with registrations methods, next it describes types of optimization principles and single criteria functions served to determine correct image transformation. Based on the theoretical part, there are realized three optimization algorithms using three criterial functions, which served to registration of provided ultrasonography sequences. These algorithms are tested and results are passed on analysis, on its ground are judged its advantages and disadvantages.

Registration of MR Images and Histological Sections
Martinásková, Klára ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
This bachelor’s thesis deals with methods of multimodal image registration. The work is focused specifically on the registration of histological sections and MR images, which various studies examine because of improving oncological diagnostics. A substantial part of the work is devoted to theories of registration - types of registration, geometric transformations, criterial functions, interpolation and methods of optimization. There is also an overview of tools, which can be used for multimodal image registration. MR images and histological sections were provided from three different sources. The program for image registration was created in software MATLAB 2020a with a graphical user interface and it includes a converter for editing images before the registration began. In conclusion, the results of registration were analyzed.
