Object selection in raster image
Fiala, Ondřej ; Pelikán, Josef (advisor) ; Kolomazník, Jan (referee)
A common task solved during a work with raster images is a object selection. Results obtained from this task are used in a number of applications - from analysis of the growth of human settlements to automatic medical diagnosis. This work describes in detail the object selection in raster images and focuses on active contours models. This work also consider extending the graphic program GIMP, bringing a new plug-in for object selection in raster images. The solution is based on the original classic model of active contours, the extended model using a gradient vector field (GVF) and proposed improvements. The work presents results obtained by this tool and brings recommendations for future development of active contours models.

Volume data editor
Kavalík, Jiří ; Kolomazník, Jan (referee) ; Krajíček, Václav (advisor)
In the present work we want to design and implement simple tool for basic editing of volume data like resizing, rotating, tresholding retouching, which could be extended as needed. Currently, there are tools for volume data visualisation and simple editors for modding computer games with voxel-based graphics. There is not an editor with basic set of tools for editing volumes in resolution of medical scanners available to common user. The designed and implemented editor can run on common hardware and oth ers set of simple brushes and filters to the user and means to implement diferent tools as plugins for C# programmer.

Tile editor
Mikeš, Marek ; Kolomazník, Jan (referee) ; Pelikán, Josef (advisor)
The aim of this bachelor thesis is to design and implement a system which can edit planar tiles. It can replace some tiles by their instances, or pattern, preserving continuity on the edges. Editor of floor conguration, editor of tiles (instances) and component visualizating a bigger part of floor will be necessary. The application will use square and rectangle tiles. It will have at least basic graphical editing commands and support for automatic or semiautomatic satisfaction of continuity between neighbouring tiles.
