Image Viewer for Windows Mobile
Miklósy, Jiří ; Kajan, Rudolf (referee) ; Svoboda, Pavel (advisor)
Over the past few years, sales of pocket pc have increased dramatically due to the devices' popularity. As a result, these devices have replaced desktop computers in an increasingly wireless world. In this bachelor's thesis, I will describe different technologies that can be used with these computers. In the following chapters, I will try to explain programming in DirectX. The aim is for the reader to be familiarized with this framework, its usage, and problem-solving techniques. In the last chapter, I propose and implement image viewer, image upload, and tagging in 3D.

Viewer of WSQ Images for Windows
Kovács, Zoltán ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
The object of this bachelor project is proposal and realization of a picture viewer for viewing fingerprint images compressed with the WSQ (Wavelet Scalar Quantization) algorithm. The reader will get to know the basic division of picture types and basic methods of compression. Also, the reader will gain an overview of the JPEG2000 and WSQ formats, familiarize with the implementation of the viewer and with the functions the viewer offers. The viewer enables to select a compressed image which is than processed and the fingerprint image is displayed. This image can be saved to a supported image format.

Advanced HDR image viewer
Wirth, Michal ; Křivánek, Jaroslav (advisor) ; Wilkie, Alexander (referee)
04.01.17 abstract.txt 1 file:///home/misa/Desktop/dp/abstract.txt The primary purpose of this thesis is to determine criteria for a high- dynamic range (HDR) image viewer accented by computer graphics artists and other users who work with HDR images produced by physically-based renderers on a daily basis. Also an overview of already existing solutions is present. Based on both of them, a new HDR viewer is designed and implemented giving an emphasis on its memory and performance efficiency. For these purposes two alternative image data layouts, Array-of-Structures (AoS) and Structure-of-Arrays (SoA), are discussed and their impact is measured on the speed of an algorithm for changing image saturation which has been selected as a representative part of whole tone mapping process of the viewer. It has turned out that the latter type of layout allows the algorithm to run about 3 times faster or more under the conditions of a defined testing environment. The thesis has two main contributions. First it gives the above users a tool which could help them when working with HDR images. Second it indicates that there may be a potential of significant speed-up of implementations of tone mapping algorithms.

Remote sensing data usage for solving of illegal permanent stands cut down issues
Introvičová, Sabina ; Hájek, Filip
It is possible to use remote sensing data for Forensic Ecotechnique: Forest and Trees expert’s assessment processing. The image data from some satellites are free on line at present time. Also electromagnetic bands numerical depiction can be obtained from the on line satellite imagery using the open source GIS Viewer QGIS. The way of remote sensing data usage for forensic experts is shown on an example of expert’s assessment regarding the cut down forest. A significant change in forest cover is possible to find when two Landsat-8 satellite images acquired at the different time are compared. We are able to obtain the height of the cut trees from the normalized Digital Surface Model. The height is a quantity needed for the cut trees reconstruction.
