Nowadays, for better image quality compression-first schemes are preferred over the conventional demosaicing-first schemes. In some high-end photography applications, original CFA images are required; in such cases lossless compression of CFA images is necessary. A fair performance is obtained for CFA images by lossless image compression methods like JPEG-LS, JPEG-2000, etc. The proposed method mainly aims at exploiting a context matching technique to rank the neighboring pixels when predicting a pixel in a CFA image. It reorders the neighboring samples such that closest neighboring samples of the same color are predicted on higher context similarity. Adaptive color difference estimation follows the adaptive codeword generation technique to adjust the divisor of rice code for encoding the prediction residues. From Simulation results, the proposed algorithm achieved a better compression performance as compared with conventional lossless CFA image coding methods. The experimental results are obtained to prove the proposed method is having best average compression ratio as compared with the latest lossless Bayer image compression algorithms using MATLAB, a technical computing language.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130683328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A report by the Energy Information Administration says that about 98 percent of CO2 emissions (or 87 percent of all CO2- equivalent emissions from all greenhouse gases) can be directly attributed to energy consumption. The major challenge of many organizations today is a desire to operate in a “green” manner, publishing principles for environmental practices and sustainability on their corporate Web. In addition, many companies are now paying some kind of carbon tax for the resources they consume and the environmental impact of the products and services they produce, so a reduction in energy consumed can have a real financial payback. In this paper, we focus on reduction in energy consumption over the full equipment life cycle as the prime motivator for “green” application design; with energy reduction as the best measure of “green-ness”. Green IT refers to the study and practice of using computing resources in an efficient, effective and economic way. The various approaches of the green IT are Virtualization, Power management, Material recycling and Telecommuting. In which Virtualization platforms can run across hundreds of interconnected physical computers and storage devices, to create an entire virtual infrastructure. Cloud computing is the concept of equal sharing of resources among nodes. Cloud virtualization refers the process of running two or more logical computer systems on one set of hardware with equal sharing of resources. The challenge of the existing system is reduction of efficiency due server virtualization. In this paper, we propose a new system that connects more number of nodes with minimum number of servers. The sole motivation of this paper is reducing energy consumption using cloud virtualization clique star cover number technique.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115044684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It records infrared radiation emitted from the Earth's surface. By absorption spectrometry, absorption and the column density of these gases can be obtained. Linear Indium Gallium Arsenide (InGaAs) photodiode detector array is employed. The array is hybrid InGaAs and CMOS active-pixel readout electronics. Detector has Spectral Resolution is approximately 6 nm. Optics employs 35 mm optics to collimate radiation from a 1 km tile onto a diffraction grating and then focus it onto the detector array. Data packets are processed and transmitted to the OBC subsystem using either RS232 interface or TLL logic at a period of 100ms.
