    In the area of musculoskeletal MR images analysis, the image denoising plays an important role in enhancing the spatial image area for further processing. Recent studies have shown that non-local means (NLM) methods appear to be more effective and robust when compared with conventional local statistical filters, including median or average filters, when Rician noise is presented. A significant limitation of NLM is the fact that thy have the tendency to suppress tiny objects, which may represent clinically important information. For this reason, we provide an extensive quantitative and objective analysis of a novel NLM algorithm, taking advantage of pixel and patch similarity information with the optimization procedure for optimal filter parameters selection to demonstrate a higher robustness and effectivity, when comparing with NLM and conventional local means methods, including average and median filters. We provide extensive testing on variable noise generators with dynamical noise intensity to objectively demonstrate the robustness of the method in a noisy environment, which simulates relevant, variable and real conditions. This work also objectively evaluates the potential and benefits of the application of NLM filters in contrast to conventional local-mean filters. The final part of the analysis is focused on the segmentation performance when an NLM filter is applied. This analysis demonstrates a better performance of tissue identification with the application of smoothing procedure under worsening image conditions.Web of Science2112art. no. 416

    Performance and robustness of regional image segmentation driven by selected evolutionary and genetic algorithms: Study on MR articular cartilage images

    Get PDF
    The analysis and segmentation of articular cartilage magnetic resonance (MR) images belongs to one of the most commonly routine tasks in diagnostics of the musculoskeletal system of the knee area. Conventional regional segmentation methods, which are based either on the histogram partitioning (e.g., Otsu method) or clustering methods (e.g., K-means), have been frequently used for the task of regional segmentation. Such methods are well known as fast and well working in the environment, where cartilage image features are reliably recognizable. The well-known fact is that the performance of these methods is prone to the image noise and artefacts. In this context, regional segmentation strategies, driven by either genetic algorithms or selected evolutionary computing strategies, have the potential to overcome these traditional methods such as Otsu thresholding or K-means in the context of their performance. These optimization strategies consecutively generate a pyramid of a possible set of histogram thresholds, of which the quality is evaluated by using the fitness function based on Kapur's entropy maximization to find the most optimal combination of thresholds for articular cartilage segmentation. On the other hand, such optimization strategies are often computationally demanding, which is a limitation of using such methods for a stack of MR images. In this study, we publish a comprehensive analysis of the optimization methods based on fuzzy soft segmentation, driven by artificial bee colony (ABC), particle swarm optimization (PSO), Darwinian particle swarm optimization (DPSO), and a genetic algorithm for an optimal thresholding selection against the routine segmentations Otsu and K-means for analysis and the features extraction of articular cartilage from MR images. This study objectively analyzes the performance of the segmentation strategies upon variable noise with dynamic intensities to report a segmentation's robustness in various image conditions for a various number of segmentation classes (4, 7, and 10), cartilage features (area, perimeter, and skeleton) extraction preciseness against the routine segmentation strategies, and lastly the computing time, which represents an important factor of segmentation performance. We use the same settings on individual optimization strategies: 100 iterations and 50 population. This study suggests that the combination of fuzzy thresholding with an ABC algorithm gives the best performance in the comparison with other methods as from the view of the segmentation influence of additive dynamic noise influence, also for cartilage features extraction. On the other hand, using genetic algorithms for cartilage segmentation in some cases does not give a good performance. In most cases, the analyzed optimization strategies significantly overcome the routine segmentation methods except for the computing time, which is normally lower for the routine algorithms. We also publish statistical tests of significance, showing differences in the performance of individual optimization strategies against Otsu and K-means method. Lastly, as a part of this study, we publish a software environment, integrating all the methods from this study.Web of Science2217art. no. 633

    Cílem bakalářské práce je popsat roli elektrárny Dukovany (EDU) v elektrizační soustavě ČR. Zvýšením výroby elektrické energie z obnovitelných zdrojů, dochází v elektrizační soustavě častěji k nedodržování kritéria N-1 a tím i ke snížení spolehlivost celé soustavy. Zvyšuje se tak riziko blackoutu soustavy, který by měl za následek velké hospodářské škody a ohrožení lidských životů. Proto spolehlivé, dobře regulovatelné a bezpečné zdroje elektrické energie jsou velmi důležité. Úvodní část práce popisuje úlohu EDU při regulaci základních elektrických parametrů v normálním provozu elektrizační soustavy. Druhá část práce se zabývá stavy a funkcí EDU při úplném nebo částečném rozpadu elektrizační soustavy. V závěrečné části je analyzován význam EDU v elektrizační soustavě ČR a budoucí vývoj s možnou výstavbou nových jaderných bloků po ukončení životnosti v roce 2035. Elektrárna Dukovany je důležitým regulátorem jalového výkonu, protože v jihovýchodní části ČR není jiná elektrárna, která by mohla jalový výkon významně regulovat. Výkon poskytovaný EDU na podpůrné služby regulace činného výkonu a frekvence v posledních letech výrazně roste. To je dáno vlivem zvýšené výroby z obnovitelných zdrojů. Při částečném rozpadu elektrizační soustavy přechází bloky do ostrovního provozu. Pokud frekvence přesáhne dovolené meze, EDU zreguluje na vlastní spotřebu. V tomto stavu může být provozována bez časového omezení. Následně se může na pokyn dispečinku podílet na obnově soustavy. Pokud blok nezreguluje na vlastní spotřebu a nejsou dostupné rezervní zdroje napájení ani nouzové dieselgenerátory, musí být co nejrychleji obnoveno napájení. Pro obnovu napájení se využívá šest na sobě nezávislých možností. Další možností obnovy napájení bude AAC síť po dokončení v roce 2014. Ta bude odolná extrémním klimatickým vlivům a bude umístěna v areálu elektrárny, čímž bude EDU více nezávislá na vnější síti.The aim of the Bachelor’s thesis is to describe the role of The Nuclear Power Plant Dukovany (Dukovany NPP) in the Czech electricity grid. Increasing of the production of electricity from renewable energy sources in the electricity grid causes more frequently compliance of N-1 criterion and it decrease the reliability of the electricity grid. The risk of Blackout increases, which would cause large economic losses and danger to the life of human beings. Therefore, reliable, good controllable and safety sources of electricity are very important. The first part of the thesis describes the role of Dukovany NPP in the process of regulation of basic electrical parameters during the normal operation of electricity grid. The second part of the thesis deals with states and the function of Dukovany NPP after full or partial disintegration of the electricity grid. Final part analyzes the importance of Dukovany NPP in Czech electricity grid and future development Dukovany NPP with possibility of the construction of new nuclear units after the end of the operation in 2035. The Dukovany NPP is an important regulator of the reactive power. There isn’t other power plant in the southeastern part of the Czech Republic, which could significantly control reactive power. The power from Dukovany NPP, which is provided on ancillary services controlling the real power and frequency has been increasing in recent years. This is due to the increasing production of renewable sources. Units switch to island operation after partial disintegration of electricity grid. If frequency exceeds the limit, the units will switch to it is own consumption. In this stage of operation at own consumption can Dukovany NPP operated without the time limit. Dukovany NPP may participate in restoring the electricity grid, based on dispatch control instruct. If switching to own consumption is not successful and back up sources and emergency’s dieselgenerator are unavailable, the power supply has to be restored as soon as possible. There are six independent solutions to restore the power supply. Next option of restore power supply will be the AAC network after the completion of construction in 2014. The AAC network will be resistant to the extreme weather and will be place it in the area of the power station, thereby Dukovany NPP will be more independent on external network.
