Abstract
Image processing techniques are applied on various kinds of images such as medical images, microscopy images and remote sensing images for improving the visual qualities of these images as ...their credibility is questioned because of poor visibility, contrast, acquired noise etc. Image enhancement is necessary for removing the visual ailment of these images. Guided image filter (GIF) has been a suitable filter for image contrast enhancement, but the controlling parameters are taken as constant values in the conventional GIF. These control parameters vary for different kind of images; therefore, require manual tuning and adjustment which is often cumbersome, time‐consuming. The proposed work modifies the existing GIF by incorporating performance improvement in terms of optimal selection of control parameters. Thus, a novel optimized guided image filter (OGIF) is developed with the help of particle Swarm optimization (PSO) algorithm. The design methodology involves contrast and edge enhancement of the images which helps in accurate detection of region of interest (ROI) as well as noise removal. OGIF automatically adjusts the value of the controlling parameters in an optimal manner on which the detection of ROI is the most dependants. Image quality assessment (IQA) of enhanced images has been carried out using measurement of enhancement (EME), peak signal‐to‐noise ratio (PSNR in dB), measure of enhancement error using entropy (EMEE), standard deviation (SD) and entropy. The incremental change in the values of EME and EMEE advocates the suitability of OGIF for contrast enhancement.

In Okinawa, outflow of red soils from the areas of public utility, developments of farmland and resort, establishments of the U. S. armed forces becomes an important social problem. Thisproblem gives ...serious damage to the sea environment, fishing industry and the tourist industry. Therefore regulation to prevent outflow of red soils took effect in 1997. This regulation obliges publicand private enterprise to some counter plans and managements for prevention of outflow of red soils. One of some counter plans is sand sedimentation tank. A measure of muddy water for effluent uses concentration of suspended solids. But this measure needs time and energy, so new measuring system is required.In this paper, the authors describe principle and method of new Measuring Equipment for Evaluation of Muddy Water (MEE). And we carried out pollution situation of the beach sand and the various chemical experiments on the some red soils (pH, Electric Conductivity, Water-Soluble Components of Soils, Fluorescent X-ray Diffraction).
As Europe enters a significant phase of re-integration of East and West, it faces an increasing problem with the rise of far-right political parties. Cas Mudde offers the first comprehensive and ...truly pan-European study of populist radical right parties in Europe. He focuses on the parties themselves, discussing them both as dependent and independent variables. Based upon a wealth of primary and secondary literature, this book offers critical and original insights into three major aspects of European populist radical right parties: concepts and classifications; themes and issues; and explanations for electoral failures and successes. It concludes with a discussion of the impact of radical right parties on European democracies, and vice versa, and offers suggestions for future research.

eBook, Book
Vascular Transport in Plants provides an up-to-date synthesis of new research on the biology of long distance transport processes in plants. It is a valuable resource and reference for researchers ...and graduate level students in physiology, molecular biology, physiology, ecology, ecological physiology, development, and all applied disciplines related to agriculture, horticulture, forestry and biotechnology. The book considers long-distance transport from the perspective of molecular level processes to whole plant function, allowing readers to integrate information relating to vascular transport across multiple scales. The book is unique in presenting xylem and phloem transport processes in plants together in a comparative style that emphasizes the important interactions between these two parallel transport systems.

Group Creativity explores the unique form of creativity that emerges from collaborating groups. Dr. Sawyer draws on his studies of jazz ensembles and improvisational theater groups to develop a model ...of creative group processes. He applies this model of group creativity to a wide range of collaborating groups, including group learning in classrooms and innovative teams in organizations. In group creativity, a group comes together to collaboratively create in real time. The creative inspiration emerges from the interaction and communication among the members, and makes the result more than the sum of its parts. The dynamic, moment-to-moment communication among jazz musicians and improvising actors is the primary topic of the book. Sawyer explores performers' close listening and sensitivity, the submerging of the ego to the group mind, and the ways that performers work together to create something better than and different from what one solitary individual could create alone. These explorations provide insight into all forms of group creativity and collaboration.
