New methods for super-resolution imaging
Kučera, Ondřej ; Rajmic, Pavel (referee) ; Špiřík, Jan (advisor)
This master's thesis deals with methods of increasing the image resolution. It contens as a description of theoretical principles and description of calculations which are wellknown nowdays and are usually used for increasing image resolution both description of new methods which are used in this area of image procesing. It also contens a method which I suggested myself. There is also a description of methods for an evaluation of image similarity and a comparation of results from methods which are described in this thesis. This thesis includes implementations of selected methods in programming language MATLAB. It was created an application, which realizes some methods of increasing image and evaluate their results relation to the original image using PSNR and SSIM index.

Video stream objective quality evaluation in MATLAB
Noghe, Petr ; Slanina, Martin (referee) ; Polák, Ladislav (advisor)
This work deals with the picture and video objective quality evaluation in MATLAB. The first part of this work describes the methods of the assessment of picture and video quality. The second part focused on the introduction of the source image coding. For the objective image and video quality evaluation an appropriate application in MATLAB was created. For the testing of the created application a several pictures and videos with different properties were used. Finally, obtained results are evaluated and discussed.

Picture Quality Analysis in Digital Television Systems
Bednarz, Robin ; Slanina, Martin (referee) ; Kratochvíl, Tomáš (advisor)
Diploma thesis deals with the analysis of quality in digital television systems and contains theoretical description of subjective and objective assessment of quality picture methods. The thesis contains short-term and long-term analysis of quality picture of terrestrial television DVB-T. Measurements and experimentations were carried out with the help of Rohde&Schwarz DVQ analyzer of picture quality and software MPEG-2 Quality Monitor and MPEG-2 Elementary stream analyzer.

Modern compression formats of digital image
Eder, Radek ; Přinosil, Jiří (referee) ; Číka, Petr (advisor)
This bachelor thesis deals with the problems of digital image compression. There are described basic color models RGB and YCbCr and conversion between them. Described are currently used codecs for digital images. JPEG compression format is discussed in more detail, which currently is still the most widely used format for digital photos. Described is a process of digitizing the image using the JPEG standard, which includes sampling, quantization and coding. Described are also formats JPEG2000, PNG and WebP. End of chapter are described methods for subjective and objective evaluation of the quality of digital image compression. Among the subjective methods include Double Stimulus Impairment Scale (DSIS) and Double Stimulus Continuous Quality Scale (DSCQS), then the objective methods include Mean Squared Error (MSE), Peak Signal to Noise Ratio (PSNR) a Structural Similarity (SSIM). Application was created as part of the work that allows you to compress the source image to the selected formats. It also allows a qualitative evaluation of compression and store the results to the file.

An alternative JPEG coder/decoder
Jirák, Jakub ; Kiska, Tomáš (referee) ; Rajmic, Pavel (advisor)
The JPEG codec is currently the most widely used image format. This work deals with the design and implementation of an alternative JPEG codec using proximal algorithms in combination with the fixation of points from the original image to suppression of artifacts created in common JPEG coding. To solve the problem, the prox_TV and then the Douglas-Rachford algorithm were used, for which special functions using l_1-norm for image reconstruction were derived. The results of the proposed solution are very good because they can effectively suppress the artefacts created and the result corresponds to the image with a higher set qualitative factor. The proposed method achieves very good results for both simple images and photos, but in the case of large images (1024 × 1024 px) and larger, a large amount of computing time is required, so the method is more suitable for smaller images.

Fiat voluntas Tua
Válek, Ondřej ; Neumayerová, Eva (referee) ; Kristek, Jan (advisor)
The project works with the thesis that the celebration of the Eucharist is not dependent on place, or that under certain conditions any space can become a liturgical space. Conversely, it is possible to consider whether the strictly liturgical space of the church can be adapted to an alternative programme that does not necessarily involve traditional church rites, while maintaining its sacred character. Using the case study of the adaptation of St. Jilja's Church in Brno-Líšeň as a case study, the project relates to the broader issues of the Czech Roman Catholic Church, which is currently in an important period of transition in terms of demography (a decline in the number of worshippers and clergy), economics (the financial separation of the Church from the state) and culture (the completion of the restitution of property, including a number of monuments).

Catechesis as an Introduction to the Mass: A Protestant's view
Živný, Tomáš ; Beneš, Ladislav (advisor) ; Opatrný, Aleš (referee)
Katecheze jako uvedení do mše : Očima jednoho evangelíka Summary Catechesis as an introduction to the Mass: A Protestant's view In my diploma thesis I address the relationship between catechesis and the Mass, namely how the believers of the Catholic Church are acquainted with what is (or is meant to be) the centerpiece of their religious life. In the first - theoretical - part of the paper I first explain what the Mass is and how it has evolved historically, which gradually leads me to the analysis of its present form and content. I then turn my attention to catechesis, whose historical development I outline as well, and to its place among the various services of the Church. I also mention the close connection between catechesis and liturgy, which both contain a dimension of the other.Another common feature of catechesis and the Mass is that they are both Christocentric, yet at the same time anthropological in their focus on man. In the second part of my thesis I deal with the practical form of introduction to the Mass, which takes place with the help of catechetical aids (catechisms, books or coloring books). I analyze these aids and then conclude with the mention of the liturgical basis of the catechesis of converts and of those who are preparing for their First Holy Communion. Keywords catechesis, Mass,...

Church Music of Johann Sebastian Bach
Staňková, Eva ; Tvrdek, Petr (advisor) ; Špačková, Alena (referee)
Annotation: Málková, Eva. Church Music of Johann Sebastian Bach. Prague: Hussite Theological Faculty, Charles University, 2012. Thesis. The aim of this thesis is to introduce church music of Johann Sebastian Bach and its theological announcement. By looking up and appraising musical-theological elements at Bach's work this thesis brings near to the reader the theological, philosophical and mystic thinking of Bach. By pre-understanding and complexity of perception of Bach's church music is possible to see deep sense and aim of artist's work. In the first (theoretical) part I am engaged in systems of thinking that could Bach's church work influence. Then I am specifying the pieces that are supposed to be church music. In the second (practical) part I am looking for musical- theological elements that could Bach be influenced with. By researching of Bach's artistic style I am trying to find correlation of musical and theological contents and I am trying to point out that the message of Bach's church work is relevant.
