Speech quality, as perceived by the users of VoIP telephony, is critically important to the update of the service. Signal quality is degraded by network layer problems including delay, jitter and packet loss. The work presented in this paper presents the spectral analysis of speech quality for narrowband and wideband VoIP. The simulation model of VoIP network under impairments is presented. The VoIP simulations are conducted for G.729A and AMR-WB speech coders at different packet loss rates. The comparison results of various speech analysis algorithms such as power density spectrum FFT etc. for both narrowband and wideband VoIP signals are presented in this paper. The results are also measured using PESQ for narrowband speech signal and WB-PESQ for wideband speech signal","PeriodicalId":358023,"journal":{"name":"2010 2nd International Conference on Computational Intelligence, Communication Systems and Networks","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122456994","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}

Sabah and Sarawak, the two Malaysian states on the island of Borneo, occupies some of the oldest and the most diverse rain forest in the world. Malaysia has a rich variety of tree species, and the wood produced from each of these has unique structure, physical and mechanical properties. The differences in woods structure and properties allow for the manufacture of woods based products with many different appearances and uses. In order to use this precious material efficiently, proper species must be used in the appropriate places. Intelligent Woods species recognition is a new application studied in the Computer Vision field to help prevent misclassifying of woods species in woods industries. Woods recognition is an implementation on identifying the different species of woods provided with the images captured for the woods samples or the characteristics observed. In this study, the features from the enhanced woods images are extracted using the LBP histogram, which determines the classification between the various woods species. The recognition is performed using a nearest neighbor classifier in the computed feature space with Chi square as a dissimilarity measure. The intelligent woods recognition system is designed to explore the possibility of developing a system which is able to perform automated woods recognition based on woods anatomy. The result thus obtained shows a high rate of recognition accuracy proving that the techniques due to its rotation invariance and robustness to gray-scale variations are very promising for practical applications.","PeriodicalId":358023,"journal":{"name":"2010 2nd International Conference on Computational Intelligence, Communication Systems and Networks","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128174052","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}

Unlike most of the ACO algorithms which consider reward-inaction reinforcement learning, the proposed strategy considers both reward and penalty onto the action probabilities. As simulation results show, considering penalty in AntNet routing algorithm increases the exploration towards other possible and sometimes much optimal selections, which leads to a more adaptive strategy. The proposed algorithm also uses a self-monitoring solution called Occurrence-Detection, to sense traffic fluctuations and make decision about the level of undesirability of the current status. The proposed algorithm makes use of the two mentioned strategies to prepare a self-healing version of AntNet routing algorithm to face undesirable and unpredictable traffic conditions.","PeriodicalId":358023,"journal":{"name":"2010 2nd International Conference on Computational Intelligence, Communication Systems and Networks","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134285070","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 main challenge of implementing these systems is a tradeoff between several factors like bandwidth, image quality, implementation cost and speed (in terms of Mega Cycles per second). Moreover to implement this Encoder-Decoder system (CODECs) in a real time system based on any Digital Signal Processor (DSP) is more difficult because of their restricted resources like memory and CPU speed. In this paper author has presented the platform specific optimization techniques for realization of a QCIF H.264 baseline encoder in a TMS320C55x DSP, which has only 256 KB RAM and 150 MHz clock speed. We achieve almost 60% MCPS reduction with respect to optimized reference encoder by applying these platform specific optimizations.","PeriodicalId":358023,"journal":{"name":"2010 2nd International Conference on Computational Intelligence, Communication Systems and Networks","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114837734","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}

Among many image enhancement approaches, the nonlinear image enhancement method has a simple structure and can obtain a good processing effect. For various target images, it is difficult to decide the best combination of clipping and scaling parameters within the nonlinear image enhancement method. In this paper, we propose a new method involving the concept of opportunity cost to simulate the image enhancement, and identify the most suitable enhancement parameters of clipping and scaling. Furthermore, a smoothing cubic B-spline filter is proposed for the conventional nonlinear image enhancement. Experimental results show that the proposed method improves the quality of blurred image and obtains a better subjective quality and objective PSNR performance than other nonlinear image enhancement methods.","PeriodicalId":358023,"journal":{"name":"2010 2nd International Conference on Computational Intelligence, Communication Systems and Networks","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123096354","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 present the NSSA(Natural Synthetic Speech Approach) to converge the same input utterances by different speakers to a new common parameter.

In this paper, we enhanced the real time speech synthesis with a novel approachfor advance noise reduction and high fidelity of the synthesizer system. According to this approach, many conventional applications such as text-to-speech synthesiscan be used more efficiently.
