Point-based editor
Remeš, Václav ; Pelikán, Josef (advisor) ; Horáček, Jan (referee)
Goal of this thesis is to implement interactive 3D editor able to work with unorganized point-clouds. Nontraditional graphics primitive needs nontraditional editing tools, author should propose and implement several instruments and verify their behavior in real editing tasks. Particular problems to be solved: efficient data representation and persistence, normal vector computation, dynamic level-of-detail, isotropic point density, etc.

Migration and load-balancing in distributed hierarchical component systems
Remeš, Václav ; Hnětynka, Petr (advisor) ; Bureš, Tomáš (referee)
A well balanced usage of resources is one of the goals of distributed applications. A way to achieve such a balanced usage is by run-time monitoring and migration of components of already executed applications between computers. There are many issues related to migration, from monitoring resources usage till obtaining component state and transferring to a di erent computer. The goal of this thesis is to design and implement a support for migration and load-balancing of components in the SOFA 2 hierarchical component system.

Texture modeling applied to medical images
Remeš, Václav ; Haindl, Michal (advisor)
and contributions This thesis presents novel descriptive multidimensional Markovian textural models applied to computer aided diagnosis in the field of X-ray mammogra- phy. These general mathematical models, applicable in wide areas of texture modeling outside X-ray mammography as well, provide ideal visual verification using synthesis of the corresponding measured data spaces, contrary to stan- dard discriminative models. All achieved results in the thesis are extensively benchmarked. The thesis presents two methods for breast density classification in X-ray mammography. The methods were tested on the widely known MIAS database and the state-of-the art INbreast database, with competitive results. Several methods for completely automatic mammogram texture enhance- ment are presented. These methods are based on the descriptive textural mod- els developed in the thesis which automatically adapt to the analyzed X-ray texture, thus being universal for any type of input without the need of further manual tuning of specific parameters. The methods' outputs highlight regions of interest, detected as textural abnormalities. The methods provide the pos- sibility of enhancement tuned to specific types of mammogram tissue. Hence, the enhanced mammograms can help radiologists to decrease their false negative...
