Full textDevelopment of methods for help diagnosis of the real time detection of abnormal cells (which can be considered as cancer cells) through bio-image processing and detection are most important research directions in information science and technology. Our work has been concerned by developing automatic reading procedures of the normal and abnormal bio-images tissues. Therefore, the first step of our work is to detect a certain type of abnormal bio-images associated to many types evolution of cancer within a Microscopic multispectral image, which is an image, repeated in many wavelengths. And using a new segmentation method that reforms itself in an iterative adaptive way to localize and cover the real cell contour, using some segmentation techniques. It is based on color intensity and can be applied on sequences of objects in the image. This work presents a classification of the abnormal tissues using the Convolution neural network (CNN), where it was applied on the microscopic images segmented using the snake method, which gives a high performance result with respect to the other segmentation methods. This classification method reaches high performance values, where it reaches 100% for training and 99.168% for testing. This method was compared to different papers that uses different feature extraction, and proved its high performance with respect to other methods. As a future work, we will aim to validate our approach on a larger datasets, and to explore different CNN architectures and the optimization of the hyper-parameters, in order to increase its performance, and it will be applied to relevant medical imaging tasks including computer-aided diagnosis

Full textDiese Diplomarbeit beschreibt die Erzeugung desktopähnlicher Anwendungen mit dem Google Web Toolkit und die Umwandlung klassischer Java-Programme in diese. Das Google Web Toolkit ist eine Open-Source-Entwicklungsumgebung, die Java-Code in browserunabhängiges als auch in geräteübergreifendes HTML und JavaScript übersetzt. Vorgestellt wird der Großteil des GWT Frameworks inklusive des Java zu JavaScript-Compilers sowie wichtige Sicherheitsaspekte von Internetseiten. Um zu zeigen, dass auch komplizierte graphische Oberflächen mit dem Google Web Toolkit erzeugt werden können, wird das bekannte Brettspiel Agricola mittels Model-View-Presenter Designmuster implementiert. Zur Ermittlung der richtigen Technologie für das nächste Webprojekt findet ein Vergleich zwischen dem Google Web Toolkit und JavaServer Faces statt

Due to highly disturbances from human developments, wetlands that are rich in ecological values are being destroyed and the number of related organisms is reduced. Analyzing the sensitive species and their habitat can improvement not only the understandings of how those sensitive species choose their microhabitat but also reflect minor changes of the environment resulting from human disturbances, hence, achieves the goal of monitoring environmental changes. This research used the semi-aquatic snakes’ survey data and the aquatic microhabitat factors to analyze the spatial distribution and the micro-habitat selection of semi-aquatic snakes. We also estimated the benefit of using multi-spectral images in aquatic microhabitat classification. Study area was located in Tau-Yuan County, where two kinds of funnel traps were set up in bogs and ponds. A total of 105 funnel traps including 15 sinking funnel traps and 90 floating funnel traps were used for capture of semi-aquatic snakes. From Sep. 2004 to Sep. 2005, a total of 49 male and 34 female Xenochrophis piscator, a total of 181 individuals, were captured. And 33 male and 36 female Sinonatrix annularis, a total of 118 individuals, were captured. Physical microhabitat factors such as water depth, mud thickness, aquatic vegetation coverage, canopy closure, grass height were measured 1 m2 around traps. The geographic information system (GIS) were used to calculate disturbance factors such as distance to lands, distance to shores, distance to houses, distance to roads, and distance to farmlands. The multivariate analyses were conducted to understand the relationship between these ten microhabitat factors and semi-aquatic snakes’ appearance frequency. Results showed that in the ponds, water depth, aquatic vegetation coverage, and distance to houses were the main microhabitat factors for X. piscator, and water depth and canopy closure were the main factors for S. annularis. In bogs, canopy closure and distance to houses were the main factors that influenced X. piscator’s microhabitat selection and water depth and distance to houses were the main factors that influenced S. annularis’s habitat selection. If the two habitat types were combined, only water depth was highly related to the appearance frequencies of the two surveyed semi-aquatic snakes. Therefore, the water depth alone was used to classify microhabitat types for ponds. Two algorisms, i.e., the maximum likely hood and minimum distance, were used for supervised classifications of multi-spectral images. The classification result showed that when few spatial pixels were available, the maximum likely hood cannot be performed. The overall accuracy of minimum distance was 70%. Different water depths were successfully classified into classes such as shallow water (water depth under 30cm), middle water (water depth 30cm~60cm), and deep water (90cm~120cm) with accuracies of 66.67%, 85.71% and 100%, respectively. Overall, the depth of water was the main microhabitat factor for both X. piscator and S. annularis in wetland habitat as a whole. Canopy coverage and aquatic vegetation may have played a minor role in microhabitat selection for X. piscator and S. annularis in different area. Both X. piscator and S. annularis appeared in the same location but may have occupied different depth of water. The human disturbances may have decreased X. piscator but increase S. annularis population. If the water depth were to be used as the major microhabitat classification factor, the multi-spectral images can be used to classify area microhabitat successfully.
