A virtualized network model for wellness information technology research

The explosive growth of Internet traffic has led to a dramatic increase in demand for data transmission capacity, which has spurred much research activities in real-time logical network construction methods. High-speed services and bulk transmission are now available, and various next-generation converged services are undergoing change as a result of demand by various services. There is also a perceived need now for video-conferencing to exchange know-how between hospitals and medical schools over cloud network. It is now time to elaborate a new wellness service incorporating diverse options. In this paper, we will examine the secure transfer of wellness information over distributed cloud network, especially medical data, and how such information should be disseminated to a network model

A Design of Architecture for Federating between NRNs and Determination Optimal Path

The current networks do not disclose information about a management domain due to scalability, manageability and commercial reasons. Therefore, it is very hard to calculate an optimal path to the destination. Also, due to poor information sharing, if an error occurs in the intermediate path, it is very difficult to re-search the path and find the best path. Hence, to manage each domain more efficiently, an architecture with top-level path computation node which can obtain information of separate nodes are highly needed This study aims to investigate a federation of a united network around NRN(National Research Network) that could allow resource sharing between countries and also independent resource management for each country. Considering first the aspects that can be accessed from the perspective of a national research network, ICE(Information Control Element) and GFO(Global Federation Organizer)-based architecture is designed as a top-level path computation element to support traffic engineering and applied to the multi-domain network. Then, the federation for the independent management of resources and resource information sharing among national research networks have been examined

Color correction for high dynamic range images using a chromatic adaptation method

In the image capturing process using a camera, poor illumination has an influence on the image quality, especially in regards to the contrast and details in the dark regions. Generally, high dynamic range (HDR) imaging techniques are used to match the quality between the real scene and the displayed image. However, in images using the multi-exposure technique or regular photography, the images are limited by the veiling glare, which is scene-, exposure-, lens-, aperture-, and camera-dependent. This study mainly addressed images using the multi-exposure technique and developed a color correction scheme that uses a chromatic adaptation method. In the tone mapping using a Gaussian pyramid, the adaptation level is obtained based on a linear Gaussian filter. The resulting image is then processed through the developed tone-mapping function. This allows the chromatic adaptation method to address the mismatches between the real world and the displayed image. The experiment results show that the proposed method yields a better color correction performance compared to conventional methods
