User's passwords are easy to hack by using different malicious programs and threats. First, Users select easy to remember password because nowadays they using many accounts on different websites. To login to websites they need to remember all passwords. So users would choose easy to remember passwords, but these passwords are not safe. Reusing passwords across different websites may cause users to lose their information which is stored in websites once the password hacked or compromised by attacker. Second, hackers can install malicious software to get the passwords, when user typing their username and password into unknown public computers.

In this paper, comparison of automatic blood vessel segmentation methods in retinal images is presented and discussed. Morphological operation for the automatic segmentation of blood vessels in retinal images has been proposed and the results are compared with matched filter technique using local entropy thresholding. Blood vessels in retinal images are enhanced by the application of matched filter. The gray levels are spatially distributed by using local entropy based thresholding. Label filtering is performed by connected pixel labeling to eliminate the misclassified and isolated pixels. The blood vessels are segmented by using morphological opening based on structuring element. These methods were evaluated on the publicly available DRIVE database and the database contains retinal images along with the ground truth data that has been precisely marked by the experts. Morphological operation is more suitable for blood vessel segmentation as compared to the local entropy thresholding.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83200464","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}

There may be different mode of communication. The communication may be wired or wireless between two links. Initially the mobile communication was limited to between one pair of users on single channel pair. Mobile communication has undergone many generations. With the rapid development of communication networks, it is expected that fourth generation mobile systems will be launched within decades. Fourth generation (4G) mobile systems focus on seamlessly integrating the existing wireless technologies including GSM, wireless LAN, and Bluetooth. This contrasts with third generation (3G), which merely focuses on developing new standards and hardware. 4G systems will support comprehensive and personalized services providing stable system performance and quality service. The future of mobile communication is FAMOUS-Future Advanced Mobile Universal Systems. The data rates targeted are 20 MBPS. That will be the FOURTH GENERATION (4G) in the mobile communication technology. 4G must be hastened, as some of the video applications cannot be contained within 3G.This paper highlights that current systems must be implemented with a view of facilitate to seamless integration into 4G infrastructure. Finally, it narrates how 4G mobile communication will bring a new level of connectivity and convenience in communication.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"90 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77263632","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}

We tackle this by using novel illumination-insensitive preprocessing method. The proposed face recognition system consists of a preprocessing stage, a hybrid Fourier-based facial feature extraction, and Principal Component Linear Discriminant Analysis (PCLDA). In the preprocessing stage, an “Integral Normalized Gradient Image”, (INGI) is obtained by transform a face image into an illumination-insensitive image. The effect of illumination gets reduced in the INGI by normalizing and integrating the smoothed gradients of a facial image. The hybrid Fourier features are extracted from three different Fourier domains in different frequency bandwidths by using a frequency band model selection, and further by adding PCLDA the robustness of the system gets improved. In face recognition, it is not possible to process with the entire extracted features, hence the dimension of the feature vectors has to be reduced. In this paper, this is done by using the linear method called PCLDA. The proposed system using the Yale B data set which is having a 2-D face images under various environmental variations such as illumination changes and expression changes.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"44 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86339694","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}

The downlink transmission of multiple video sequences to multiple users over a shared resource-limited wireless channel, however, is a tough task. We face many challenges in this area like time-varying channel conditions, limited available resources, such as bandwidth and power, and the different transmission requirements of different video content. This work takes into account the time-varying nature of the wireless channels, as well as the importance of individual video packets, to develop a cross-layer resource allocation and packet scheduling scheme for multiuser video streaming over wireless networks. Assuming that accurate channel feedback is not available at the scheduler, random channel losses combined with complex error concealment at the receiver make it impossible for the scheduler to determine the actual distortion of the sequence at the receiver. Therefore, the objective of the optimization is to minimize the expected distortion of the received sequence, where the expectation is calculated at the scheduler with respect to the packet loss probability in the channel. The expected distortion is used to order the packets in the transmission queue of each user, and then gradients of the expected distortion are used to efficiently allocate resources across users.","PeriodicalId":6426,"journal":{"name":"2013 International Conference on Emerging Trends in VLSI, Embedded System, Nano Electronics and Telecommunication System (ICEVENT)","volume":"20 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90908784","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}
