The first part of this project is about speech synthesis. From the all type of synthesis only diphones synthesis is discussed further, because its features for a mobile cell phone are superior, compared to the other types. This work further analyses implementation of speech synthesiser -this means loading of database, synthesis, creating of annotation file and creating the output sound signal. Final syntheses speech utterance is played together with face animation of talking human face. In second part is described design and implementation of face animation for mobile phone. The last part is conclusion and possibility of improvement of synthesis.","PeriodicalId":170000,"journal":{"name":"ELMAR 2007","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126939839","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 article describes advantages of H.264/AVC in mobile communication systems with limited bandwidth. Due to very efficient compression method H.264/AVC enables and provides transport of high quality video on low data rates. In order to demonstrate these abilities we made a comparison of H.264/AVC coding technique with MPEG-4 ASP (advanced simple profile) coding technique currently used in mobile systems. Quality measurement and assessment of encoded video test sequences was performed with peak signal to noise ratio (PSNR), video quality metric (VQM) and structural similarity (SSIM) objective quality measurement methods. Results showed and confirmed great efficiency and performance possibilities which will make H.264/A VC ubiquitous coding technique of multimedia world in time to come.","PeriodicalId":170000,"journal":{"name":"ELMAR 2007","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124411019","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 speech extraction is carried out using an approximation of the kurtosis measure in a subband domain. The introduced kurtosis approximation is an improvement of a recently proposed approximation technique where a locally quadratic criterion was solved at each iteration. The improvement introduced in this paper regards an approach to normalize this same criterion using a pre-processing automatic gain control unit, and thereby making the algorithm invariant to input signal scales. The proposed method outperforms the recent technique in terms of signal to interference ratio improvement. In addition, the increased memory consumption and processing load due to the proposed improvement is comparably low and this is often desirable in a realtime digital signal processor (DSP) implementation. Further, a real-time implementation of the method is conducted and results with real data is presented.","PeriodicalId":170000,"journal":{"name":"ELMAR 2007","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134120297","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 monomodal classification results for these two problems and discuss whether multimodal classification seems to be promising for the respective problem.

Instead of lognormal probability density function (PDF), gamma PDF is used for shadowing while multipath fading is represented with Nakagami-m and Rice distributions. A mathematical framework is developed for deriving key statistical parameters such as PDFs of signal to noise ratio (SNR) and signal to interference ratio (SIR) of several special scenarios in mobile channel as well as performance metrics including outage probability. In this way, one can conclude that presented results are reliable for lognormal shadowing spread <9dB (note that, the shadowing spread actually observed in macro-cells has a typical value that lies between 4 and 9 dB). The final results are remarkably simple and can serve as a quick way of assessing performance. In addition, presented analytical expressions are suitable for the asymptotic analyses, which is significant feature for both theoretical and practical aspect of theirs applications.","PeriodicalId":170000,"journal":{"name":"ELMAR 2007","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116764221","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}
