A Novel Metric Approach Evaluation For The Spatial Enhancement Of Pan-Sharpened Images

Various and different methods can be used to produce high-resolution multispectral images from high-resolution panchromatic image (PAN) and low-resolution multispectral images (MS), mostly on the pixel level. The Quality of image fusion is an essential determinant of the value of processing images fusion for many applications. Spatial and spectral qualities are the two important indexes that used to evaluate the quality of any fused image. However, the jury is still out of fused image's benefits if it compared with its original images. In addition, there is a lack of measures for assessing the objective quality of the spatial resolution for the fusion methods. So, an objective quality of the spatial resolution assessment for fusion images is required. Therefore, this paper describes a new approach proposed to estimate the spatial resolution improve by High Past Division Index (HPDI) upon calculating the spatial-frequency of the edge regions of the image and it deals with a comparison of various analytical techniques for evaluating the Spatial quality, and estimating the colour distortion added by image fusion including: MG, SG, FCC, SD, En, SNR, CC and NRMSE. In addition, this paper devotes to concentrate on the comparison of various image fusion techniques based on pixel and feature fusion technique.Comment: arXiv admin note: substantial text overlap with arXiv:1110.497

Computer Network Performance Evaluation based on Datarate and Number of Clients Per Server using OMNeT++ Simulation Environment

We present the performance of Computer network using OMNeT++ network simulation framework and Nclient application module from INET framework for our experiment. Present paper is the study of how datarate in affecting the performance of Computer Network. Main aim of the study is to find out the best configuration network setup to get optimum Network throughput. The performance of the Network is measured in terms of throughput

ICT: A Tool for sustainable Rural Development

ABSTRACT The major population of entire world lives in rural area and earns its live hood by agriculture and allied means. Rural area experiences hunger and poverty. The rural community is isolated from the world. They can't present themselves in front of the world. Development in 21 st century will determine to a large extent by the thought, action and imagination of people. Computers are reshaping human lives. In the rapidly changing scenario, the extensive use of computers advances in ICT making sustainable rural development possible. The paper introduces the role of ICT for rural development. The paper addresses the issues associated with rural community's isolation. ICT can reduce digital divide between urban and rural community. In order to alleviating poverty in rural areas, ICT can be used. ICT provides rural communities with existing possibilities for overcoming the disadvantages associated with countrymen's isolation and provides linkages upon opportunities for enhancements. The paper concludes that effective use of ICT can demolish geographical boundaries and can bring rural communities closer to globe. ICT in right direction can play a vital role for betterment of society and the rural community. There is a critical need to channel the vast potential of information technology to underprivileged.
