Many simulation models have been proposed in this direction, with Clarke's model as the reference model which was later simplified by Jake's model, which could not maintain the wide-sense stationary characteristics. Then an improved model was proposed by Pop and Beaulieu which was further modified by Zheng and Xiao. In this paper, we have considered that the probability of angle of arrival of received signal is not same in the entire range but is assumed high between -π/2 to π/2 and is assigned small value in the remaining ranges -π to -π/2 and π/2 to π. However in each segment the angle of arrival of received signal is considered to have uniform probability distribution function. This proposed probability distribution for the angle of arrival seems to be more realistic in some practical scenario. The autocorrelation, probability density function and power spectral density of the fading envelop is in close agreement with the mathematical model proposed by Clark.","PeriodicalId":402311,"journal":{"name":"Proceedings of the 2015 Third International Conference on Computer, Communication, Control and Information Technology (C3IT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132617474","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}

Script identification has numerous applications in the field of document image analysis, such as document sorting, indexing, retrieval and translation, etc. In this paper, we have developed a page-level script identification technique for handwritten documents using the texture features. The texture features are extracted from the document pages based on the Gray Level Co-occurrence Matrix (GLCM). The proposed technique has been evaluated on four scripts namely, Bangla, Devnagari, Telugu, and Roman using multiple classifiers. Based on their identification accuracies, it is observed that Multi Layer Perceptron (MLP) classifier performs the best. The experimental results demonstrate the effectiveness of the GLCM features in identification of handwritten scripts. Experiments are conducted on a total of 120 document pages and the overall accuracy of the system is found to be 91.48%. Though the system is evaluated on limited dataset, considering the complexities of the scripts, the result can be assumed satisfactory.","PeriodicalId":402311,"journal":{"name":"Proceedings of the 2015 Third International Conference on Computer, Communication, Control and Information Technology (C3IT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129089561","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}

This paper describes detection of the facial landmarks of UGC-DDMC face database which includes left eye corners, right eye corners, left eyebrows, right eyebrows, lip corners, nostrils. It consists of two parts: In first part, a morphological opening operation is used to estimate the background. Then create a more uniform background by subtract the background image from original image. In the second part, the facial landmarks had been detected using Fast corner detector technique. The Fast corner detector works on the corner response function (CRF), which is computed as a minimum change of intensity over all possible direction. The Fast corner detector is significantly faster to compute than other algorithms. The experiment has been done over the UGC-DDMC Face Database of Tribes of, which is being developed by IT Department of Dasaratha Deb Memorial College, Khowai, Tripura. In our Experiment initially we used 108 Facial images with different pose from the UGC-DDMC Face Database and 110 images from IRIS Database. Performance results for ntIS database is 100% and UGC-DDMC Database is 74%. It has been seen that algorithmic performance is high with low threshold value and with higher values if shows good performance. Fiducial points obtained during this process will be useful for any feature based Face recognition process. Thus, we can justify the design process of the UGC-DDMC Face Database.","PeriodicalId":402311,"journal":{"name":"Proceedings of the 2015 Third International Conference on Computer, Communication, Control and Information Technology (C3IT)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114615120","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}

Due to the high mobility of nodes, the network topology of MANETs changes very fast, making it more difficult during data transmission of data packet from source node to destination node. Because mobile nodes have limited battery power, it is therefore very important to use energy in a MANET efficiently. Due to the dynamic topology and limited resources of mobile nodes, the routing scheme in MANETs presents important challenges. In this study, load balancing multicast routing protocol (LBMRP) for MANETs is proposed. In the proposed scheme, all mobile nodes are randomly classified into three types, group-1, group-2 and group-3. To achieve the load balance, three multicast trees (TREE-1 for group-1, TREE-2 for group-2 and TREE-3 for group-3) are constructed. Simulation results show that the proposed LBMRP scheme outperforms multicast ad hoc on-demand distance vector routing protocol (MAODV), reliability of the multicast ad hoc on demand distance vector (RMAODV) and Parallel multiple nearly-disjoint trees multicast routing (Parallel MNTMR) schemes.","PeriodicalId":402311,"journal":{"name":"Proceedings of the 2015 Third International Conference on Computer, Communication, Control and Information Technology (C3IT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122611383","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}
