Segmentace obrazu jako výškové mapy / Image Segmentation Using Height MapsMoučka, Milan January 2011 (has links)
This thesis deals with image segmentation of volumetric medical data. It describes a well-known watershed technique that has received much attention in the field of medical image processing. An application for a direct segmentation of 3D data is proposed and further implemented by using ITK and VTK toolkits. Several kinds of pre-processing steps used before the watershed method are presented and evaluated. The obtained results are further compared against manually annotated datasets by means of the F-Measure and discussed.

Vytěžování textu z fotografií / Optical Character Recognition at Camera Captured ImagesKindermann, Hubert January 2014 (has links)
We present solution of steps necessary for binarization and text lines detection contained in printed documents digitized by the camera. We introduce a normalization of non-uniform illumination method for text photographs. We propose input bitmap binarization algorithm based on two-dimensional probability pixel model which also considers its surrounding. We continue with description of robust text lines orientation detector based on optimization of risk function using first order derivatives of image function. In the end we present text lines detection and segmentation algorithm. Final shape of segmented lines is optimized with usage of graph algorithm. Powered by TCPDF (www.tcpdf.org)

Klasifikace dat leteckého laserového skenování s využitím informace o intenzitě a šířce zaznamenaného signálu / Classification of airborne laser scanning data using information about intensity and width of the recorded signalPetr, Peter January 2012 (has links)
Classification of airborne laser scanning data using information about intensity and width of the recorded signal Abstract One of the basic tasks in analysing airborne laser scanning (ALS) data is filtration of mass 3D point cloud with purpose to create digital terrain model and digital surface model. New scanner generation (so called Full-waveform LiDAR) allows analysing the whole recorded signal. The recorded value of amplitude and signal width accordant with reflectance of different objects differs according to geometry of the objects. Objective of this thesis is to create a methodology for classification of ALS data in settled areas. This methodology will be based on number of reflections, amplitude of reflected signal, recorded signal width and on spatial attributes. At the same time it will be analysed how the parameters of amplitude and signal width are affected by characteristics of estate surface. It means which radiometrical characteristics (e.g. different roof materials) and geometrical characteristics (e.g. different roof inclination) belong to which amplitude and signal width. Basic question of this thesis is if amplitude and signal width are good attributes to improve the quality of filtration of mass 3D point cloud in chosen area and if so, how. Key words: classification, segmentation, LiDAR,...

Finanční geografie - aplikace vybraných konceptů v podmínkách České republiky / Financial Geography - An Application of Selected Concepts in Terms of the Czech RepublicBečicová, Ilona January 2013 (has links)
FINANCIAL GEOGRAPHY - AN APPLICATION OF SELECTED CONCEPTS IN TERMS OF THE CZECH REPUBLIC Abstract The aim of the thesis is to analyse the main trends of banking system in Czech Republic after 1989. It is primarily an analysis of centralised banking system, on the basis of which the potential regional impacts according to theory of regional segmentation of fiancial markets are tested. Based on the analysis of changes in the distribution of bank headquarters and the analysis of employment in financial sector it is clear, that in terms of the Czech Republic a highly concentrated banking system occured, which is moreover under the strong inluence of foreign capital. The study focused on testing the regional impacts of a centralized system through interviews with business owners in the peripheral region has not proved allegation of discrimination of entrepreneurs in such manner as we would expect according to the theory of regional segmentation of financial markets. However the study showed some problems with providing guarantees for bank loans in the periphery.

Lifestyle market segmentation - efficiency and ethical issues / Tržní segmentace podle životního stylu - Efektivnost a etické aspektyPilstl, Michaela January 2010 (has links)
Lifestyle market segmentation can be very supportive for a successful marketing strategy of a company. However it is not clear whether lifestyle market segmentation is efficient and ethical or not. Several market segmentation concepts such as Cross-Cultural Consumer Characterization, VALS, PRIZM NE, Mosaic, ConneXions NE and GfK Roper Consumer Styles are analyzed in order to give an extensive overview of the offered concepts. The observation of efficiency issues in regards to market segmentation comes to the result that there is a significant lack of empirical data and a shortage of determined factors which can improve market segmentation efficiency. Moreover, lifestyle market segmentation cannot be exclusively identified as ethically right or wrong, but depends on the individual ethical decision-making of a marketer.

Analýza postojů vybraných segmentů spotřebitelů k jednotlivým typům prodejen (malé prodejny, super- a hypermarkety ap.) / Analysis of consumer attitudes to the various types of storesPuchtová, Kateřina January 2010 (has links)
This thesis deals with analysis of consumer attitudes to various types of stores. Its goal is to determine these attitudes and define the various segments of consumers who go shopping in those stores. Further to recommend an appropriate marketing strategy on the basis of the obtained results. The thesis is dividend into two parts. The first theoretical part prepares a theoretical basis for the second part, which is own research on consumer attitudes in Pilsen and environs. The first part of the theoretical basis defines the different types of stores. They differ in many characteristics and their combinations. The second part deals with the attitudes. It includes definitions of attitudes, defines their components, determines the attributes and functions, their formation and possibilities of change. The third section focuses on the segmentation. What segmentation is, how it is done and what is its aim. The fourth section describes the various ways of marketing communications and defines its goal. It also deals with psychological reasons for buying and own trade mark. In the second practical part I achieve own market research, whose goal is analysis of attitudes of pilsener consumers to the various types of stores.
