Title: Analytics module for the Videolytics system Author: Petr Pechman Department: Department of Software Engineering Supervisor: prof. RNDr. Tomáš Skopal, Ph.D., Department of Software Enginee- ring Abstract: Videocameras and monitoring devices are widely used in public space. With the growing number of these devices, manual data analysis becomes ineffici- ent, so the goal is to obtain efficient automatic video processing. The Videolytics system is a web-based system for advanced video analytics. It is built on the de- tection of simple objects concentrating in a database. This work is an extension of the Videolytics system with by complex analysis. The analytics module provi- des processing of complex queries that are created by user. The formulation of a complex analytical query is natural for users, but the exact deĄnition of a query for a computer system is complicated. Analytical queries consist mainly of al- phanumeric and spatial predicates, which are analyzed by the module, and based on them, an exact SQL query is generated. At the same time, the module also provides functionality for direct execution of an SQL query on a database. The combination of the analytics module and the user interface creates an advanced user tool for analytics, which has great use because of its generality. Keywords:...

Growth performance of containerized and bare-rooted planting stock
Pechman, Petr ; Kuneš, Ivan (advisor) ; Otakar, Otakar (referee)
The aim of this thesis is to analyze the development and growth of containerized and bare-rooted seedlings of Norway spruce on the plots situated on the Dolní Lomnice Forest District, a division of Karlovy Vary VLS ČR, s. p. (Army Forest and Estates of the Czech Republic). In this work addressed the following sub-tasks: comparison of mortality, height increment and increment of root collar, root development, analysis of cost recovery stands on the site.
Three years after the founding of the plots it was discovered that containerized planting stock reached higher relative increment. When using a planting hole technology, the mortality was in both types of planting stock approximately similar. Furthermore, it was found that containerized planting stock planted with the planting hole technology, a higher incidence of advent naturally developed roots occurred. The planting technology using a loading mandrel (similar typesetter) used for containerized planting stock was assessed as an unsuitable and also the most frequent presence of unnatural root architectonics (deformations and secondary roots, if they were ever developed) it was demonstrated. An economic study showed that the overall costs for the forest regeneration using of the containerized planting stock are higher compared with the bare-rooted planting stock.
