The procedure of forensic photography requires that the film plane should be paralleled to a taken image. Another procedure must be followed when the print is located on reflexible surfaces such as vehicles, or faint marks on porous surfaces. Examinations were made of the evidential value of mark images which were received from the scene or taken deliberately at an angle out of proper perspective (i.e., the lens axis is not perpendicular to the target plane). Based on geometry of differential and projection as well as the theory of imaging optics, a robust and fast inclination rectification algorithm is proposed using perspective transform of camera lens, and validated using MATLAB.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117325835","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 sampling and testing result shows that the accuracy in this case reaches as high as 86%. It can be easily concluded that Decision tree is an effective way for the agriculture land grading.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123556105","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}

With the help of the USB Key and fingerprint, people have developed kinds of authentication solutions [1, 2, 3] to protect the confidential information against unauthorized access. After some research, we found that the above solutions have two serious problems. One is that the sensitive information is not encrypted; the other one is that the environment is insecure. In this paper, we developed a new high-level security portable system to solve these problems. The system is a combination of hardware and software. On the one hand, based on the USB Key and fingerprint scanner, we integrated a plug-and-play USB2.0 device without driver installation. On the other hand, by rebuilding the syslinux boot loader and customizing the Puppy Linux and doing some special works on the USB flash partition, we have developed and integrated a fingerprint-based authentication security portable custom-built software environment inside the USB device. With the help of the system, the users can work at a movable security environment freely, as well as the high-level protection of confidential information.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122003894","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}

To perform better resource utilization and proper resource allocation, the factor job runtime is essential. Accurate estimation of runtime helps to reserve resources in advance, provide user level QoS. But it is difficult to estimate the runtime of data intensive applications. Users are required to provide the runtime estimate of the job, but the user given estimates are inaccurate leading to poor scheduling. In this paper, we have used rough set techniques to analyse the history of jobs and estimate the runtime of the job. This requires maintaining a history of jobs that have executed along with their respective runtime. Our proposed rough set engine groups similar jobs and identifies the group to which the newly submitted job belongs. Based on this similar group identified, the runtime is estimated. Mostly users are not aware of resources, submitting incomplete job requirements. These missing job requirements affect data analysis. Those missing values should be accurately predicted. Missing value handler designed using rough sets fills the most probable value for missing attributes and then the runtime is estimated.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122022803","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 error rates of such systems can significantly be decreased just by detecting and removing poor quality images right at the early stages. In this paper, an effective quality estimation scheme is proposed, which performs analysis in hierarchical fashion. This multilayered quality analysis comprises eight quality measures, three at global level (whole image)) and five at local level (block-wise), each one giving its respective quality score. The scores at their respective levels are fused into a single quality score by their corresponding fusion engines at two different levels. Fusion engines are based on the ‘Weighted Sum rule’. The scheme is also evaluated using ‘Sum rule’. The proposed scheme is experimented against fingerprint Verification Competition (FVC 2004) datasets. The experimental results show that this arrangement could correctly estimate and assign grades (good/acceptable/poor) to nearly 95% images in the dataset. Also, it is observed that this novel fusion-based hierarchical quality assessment model estimates fingerprint quality more effectively with ‘weighted sum rule’ than ‘sum rule’ and their individual counterparts.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126002858","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}

First, the nth Radius-Weighted-Mean Points (RWMPs) are proposed which are invariant to translation, rotation and scaling, and then, a RWMP-based feature vector is constructed which is still invariant to translation and rotation. The candidate referenced star images and their corresponding attitudes are obtained by computing the Euclidean distance between the viewed star image and each of the star images in the pattern database. The verification process is introduced to confirm the identification results. The simulation results indicates that the average identification rate of this algorithm can be enhanced 3.5% as compared to the grid algorithm at the same position noise level from 0 to 3 pixels, and the identification time of the proposed algorithm reduces to 1/5.","PeriodicalId":190625,"journal":{"name":"2010 International Conference On Computer Design and Applications","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125082366","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}
