Compression reduces the storage and transmission burdens of raw information by reducing the ubiquitous redundancy without losing its entropy significantly. The image manipulation that occupies a significant position in multimedia technology necessitated the development of joint photographic experts group (JPEG) compression technique, which has proved its usefulness so far. Until recently, to minimize the blocking artifact, inherently present in JPEG at higher compression ratios, JPEG2000 is devised that makes use of wavelet function. In this work, a new approach to JPEG compression technique is proposed that enhanced the compression performances in comparison with aforesaid JPEG techniques. The new technique considers both discrete cosine transform (DCT) and singular value decomposition (SVD) method in the transform and reconstruction sides instead of using DCT only. The incorporation of SVD with nearest neighborhood approach has improved the compression performances significantly. A rigorous comparison of the various compression indices are made to validate the proposed algorithm. This approach is named as 'Hybrid JPEG' (HJPEG) in this paper. The benchmark still image 'LENA' is used for performance comparison.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127295554","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}

Existing algorithms for drawing such graphs either impose restrictions on the number of vertices or use intricate mathematical concepts that make the drawing less comprehensive. Moreover, they are incapable of depicting the attributes of vertices and edges, which is often a requirement. In this paper, we present two 3D graph drawing conventions which can overcome these problems. We also show that it is possible in our convention to draw trees and series-parallel graphs with volume bounds of O(kn) and O(n2 log n) respectively, where k is the maximum degree of any vertex in the tree.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125066702","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 speaker features represented by the speech signal are potentially characterized by the cepstral coefficients. The commonly used cepstral based features; mel-frequency cepstral coefficient (MFCC), linear predictive cepstral coefficient (LPCC) and real cepstral coefficient (RCC) are employed with DHMM in the speaker identification system. The performances of the proposed method are compared with respect to each of the three feature spaces. The experimental results show that the identification accuracy with MFCC is superior to both of LPCC and RCC.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129675892","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}

One of the key challenges in microarray analysis, especially in cancerous gene expression profiles, is to identify genes or groups of genes that are highly responsible for the existence of a tumor in a cell. Our proposed modified algorithm support vector machine (SVM) is used to classify cancer related 5 microarray data and observed improved performance than previously used Interesting rule group (IRG), classification based on associations (CBA), and even a different version of SVM algorithm. Finally we use entropy measure through rule based learning algorithm to extract the responsible genes causes for cancer for each microarray problem.

This paper reviews the type of noise present in power line channel at narrowband, and noise measurement was carried out on the indoor low-voltage network at the frequency range from 20 kHz to 500 kHz. The results were used for the consideration of a robust and simple narrowband PLCM design. The modem was built upon the ATMEL microcontroller 89C51 chip to achieve reliable performance and reduced hardware complexity, and economic system. Master-slave architecture with RS-232 asynchronous serial communication has been followed. Proper carrier frequency-band and modulation schemes immune to synchronous impulse noise in low-voltage power line communication were suggested.","PeriodicalId":206443,"journal":{"name":"2007 International Conference on Information and Communication Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131263215","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}
