Common Image Stereo-Pair Processing for Simple Stereo-Geometry
Peloušek, Jan ; Schimmel, Jiří (referee) ; Říha, Kamil (advisor)
This Bachelor´s thesis considers the basics of epipolar geometry, explains the process of the automatic correspondency detection, describes principals of the fundamental matrix computation and finally the virtual camera view morphing between two images. There were described some of the basic Intel´s OpenCV library functions joined with this issue and describes de facto the computer stereo-pair processing. As a part of this thesis, there is the application, programmed in the C++ language in the Borland C++ Builder 6.0 developer´s environment by using the OpenCV library. This application demonstrates some of here-mentioned terms such as the fundamental matrix computation and the virtual camera view morphing. In relation to the Borland C++ Builder 6.0 using there was described the integration method of OpenCV to this environment.

Detection and Correspondence of Image Features
Hasmanda, Martin ; Kohoutek, Michal (referee) ; Říha, Kamil (advisor)
The main goal of this bachelor‘s thesis was obtain basic knowledge about image processing. Especially was this work specialized on features detection in images captured from different perspectives and for finding correspondences between those images. Preliminary were to be described the basic principles for understanding computer vision such as perspective projection, description model of the camera and two views geometry. From methods of the detection was introduced best-known and most widely used of the detectors Harris corner detector. He is independent of images rotation and he is analyzed in detail. Further was described SIFT detector, that is independent of images scale. In this work further be described to several methods for finding correspondences of images features. First were to be described and derived two basic transformation matrixes that arrange to the association with features of two images. The first homography matrix describes transformation of two 2D views and fundamental matrix. Fundamental matrix obtains from two images full information of captured 3D scene and projection matrixes of cameras. For to primary definition correspondences were to be used to methods SSD and NCC. These methods match correspondences after similarities surroundings of features. These methods unfiled correct assignment features. Therefore uses stochastic RANSAC algorithm. The RANSAC algorithm was in detail described in this work in basic form and further modified on MLESAC algorithm. This algorithm can find better correspondences than RANSAC. In the end was described simple application for implementation introduced methods.

Processing of Stereoscopic Video Sequence
Hasmanda, Martin ; Šmirg, Ondřej (referee) ; Říha, Kamil (advisor)
The main goal of this master’s thesis was get up used methods for observation the stereoscopic scene with one couple of cameras and find out good solving for processing these resulting pictures for two-view and multiple-view autostereoscopic displays for three-dimensional perception. For methods for acquisition video was introduced two methods. They were method “Off-axis” with parallel camera axis and method “Toe in” with intersections axis. For fit method was choice the method named as “Off-axis“. It was not produces the vertical parallax and in detail was in this work described principle of this method. Further were describe principles off used methods for three-dimensional perception namely from the oldest method named anaglyph after methods for viewing at autostereoscopic displays. The Autostereoscopic displays were main goal of this thesis and so their principles were described in details. For production the result image for autostereoscopic displays was used generation intermediate images between left and right camera. Resulting videos were acquisition for testing scene in created in 3D studio Blender, where was possible setting system of cameras exactly parallel axis. Then were introduce principles processing video where was extract from the couple of cameras where were connected to PC for help digitizing card and next time with two web cameras. Here is not guaranteed exact parallel axis system. Therefore this work try for real cameras achieve exactly parallel axis system by the help of transformations of frames with stereo rectification. Stereo rectification was solving with OpenCV libraries and was used two methods. Both methods work from principles epipolar geometry that was described in this work also in detail. First method rectifies pictures on the basis fundamental matrix and found correspondences points in two images of the scene and second method rectifies pictures from knowledge intrinsic and extrinsic parameters of stereoscopic system of cameras. In the end of this work was described application for implementation introduced methods.

"My dear friend alias Panerado". Vladimír Holub in the personal Corrrespondence and cultural Context of 20th Century.
TREPKOVÁ, Šárka
This thesis focuses on the personality of Vladimir Holub (1912-1995), the South Bohemian artist and an unjustly neglected solitaire who, with his contribution to Czech modern art, belongs to an important but so far unmapped chapters of the Czech cultural history. Vladimir Holub is primarily associated with Surrealism. In addition to his artwork and sculptural work, remarkable is also his rich correspondence with many leading personalities of national and world art and literature. This thesis focuses at this correspondence, which is stored in the PNP The thesis is divided into several chapters, in which the author interprets Holub's life based on several key areas, which were essential in his life. The main topics are politics, art (and especially literature) and friends. Their importance will be documented in subsequent correspondence, which brings a cut through Holub's intellectual life as well as his life and work. In the beginning the author captures Holub's detailed biography, which is completed directily with his memories or memories of his closest friends. That demonstrates the artist's unique proof of authenticity. Despite the adversity, at the time of his being, Vladimir Holub is trying to retain his artistic and intellectual identity, which is also analyzed by the author of the thesis.

Selected Letters of Vladimír Holan
DVOŘÁK, Martin
Vladimír Holan is one of the most important Czech poets of the 20th century. However, his rich correspondence with plenty of significant people of Czech culture is out of broad the concern of literary scientists. The Holan's correspondence is the main deal of this diploma theses and for its purpose the student will collect, classify and prepare for potential edition a part of poet's correspondence. The selection of correspondence of Vladimír Holan, which is deposited in The Literary archive of The Museum of Czech literature in Prague, will be consisted of approximately ten letter-conversation threads between Vladimír Holan and the significant people of Czech cultural context mainly. The thesis will also include the study in which the student will try to interpret the change of Holan's period poetics by analysis of Holan's statements the convolute of the selected letter will contain.
