Accurate tumor segmentation has the ability to provide doctors with a basis for surgical planning. Moreover, brain tumor segmentation needs to extract different tumor tissues (Edema, tumor, tumor enhancement, and necrosis) from normal tissues which is a big challenge because tumor structures vary considerably across patients in terms of size, extension, and localization. In this article, we evaluate a fully automated method for segmenting brain tumor images from multi‐modal magnetic resonance imaging volumes based on stacked de‐noising auto‐encoders (SDAEs). Specially, we adopted multi‐modality information from T1, T1c, T2, and Flair images, respectively. We extracted gray level patches from different modalities as the input of the SDAE. After trained by the SDAE, the raw network parameters will be obtained, which are adopted as a parameter of the feed forward neural network for classification. A simple post‐processing is implemented by threshold segmentation method to generate a mask to get the final segmentation result. By evaluating the proposed method on the BRATS 2015, it can be proven that our method obtains the better performance than other state‐of‐the‐art counterpart methods. And a preliminary dice score of 0.86 for whole tumor segmentation has been achieved. 相似文献

在意大利举办的2015国际纺织机械展(ITMA)上,纺织机械制造商们展示了机器及最新研发,由此可以得出纺织工程最新的发展趋势。迫于中国纺机制造业的竞争威胁,ITMA 2007展出了一些功能缩减的较低价的机器。但ITMA 2011则展出了多种具有革命性改进的机型,如苏拉欧瑞康(Saurer Oerlikon)公司开发的Autocoro 8转杯纺纱机,其每个纺纱锭位完全自动化,并运用了磁力轴承转子;立达(Rieter)公司的喷气纺纱机J 10及迈耶西(MayerCie)公司的全新纺纱-编织一体机理念。ITMA 2015则展有许多虽小但高效的革命性创新,可显著降低客户的生产要素成本。 相似文献

BackgroundInsects are touted as a “food of the future” due to their lower environmental footprint relative to traditional livestock, raising interest in entomophagy as a sustainable diet. As such, they appeared at future-food themed Universal Exposition 2015 in Milan, Italy, in which 145 countries presented their nations’ food culture and contributions to innovative food science and technology.Scope and approachThe presence and absence of entomophagy in all the national and themed pavilions of Expo 2015 and the way developing and developed nations differed in their presentation of insects were analyzed as a microcosm of global attitudes to insects as food and the barriers towards its wider adoption.Key findings and conclusionsOnly Belgium and the Netherlands presented insects in their vision for the future, and only Angola as traditional cuisine. Nations noted for active entomophagy today such as Mexico and Thailand did not mention insects at all. Efforts to serve insects faced obstacles in Italian import restrictions, which changed by the event's end. Expo 2015 illustrates challenges in promoting global entomophagy, including the need for improved rearing methods, the risks of associating insects with starvation scenarios, and the preference of Westerners for processed insects over whole. 相似文献
