The present method uses a weighted mesh median filtering technique for smoothing. In this present smoothing technique we have built the neighborhood surrounding a particular point in 3D face and replaced that with the weighted value of the surrounding points in 3D face image. After applying the smoothing technique to the 3D face images our experimental results show that we have obtained considerable improvement as compared to the algorithm without smoothing. We have used here the maximum intensity algorithm for detecting the nose-tip and this method correctly detects the nose-tip in case of any pose i.e. along X, Y, and Z axes. The present technique gave us worked successfully on 535 out of 542 3D face images as compared to the method without smoothing which worked only on 521 3D face images out of 542 face images. Thus we have obtained a 98.70% performance rate over 96.12% performance rate of the algorithm without smoothing. All the experiments have been performed on the FRAV3D database.","PeriodicalId":148511,"journal":{"name":"International Conference on Pattern Recognition, Informatics and Medical Engineering (PRIME-2012)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116715867","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}

Even though, RSA (Rivest-Shamir-Adleman) was the most prominent cryptographic scheme, it is being replaced by ECC in many systems. This is due to the fact that ECC gives higher security with shorter bit length than RSA. In Elliptic curve based algorithms elliptic curve point multiplication is the most computationally intensive operation. Therefore implementing point multiplication using hardware makes ECC more attractive for high performance servers and small devices. This paper gives the scope of Montgomery ladder computationally. Montgomery ladder algorithm is effective in computation of Elliptic Curve Point Multiplication (ECPM) when compared to Elliptic Curve Digital Signature Algorithm (ECDSA). Compactness is achieved by reducing data paths by using multipliers and carry-chain logic. Multiplier performs effectively in terms of area/time if the word size of multiplier is large. A solution for Simple Power Analysis (SPA) attack is also provided. In Montgomery modular inversion 33% of saving in Montgomery multiplication is achieved and a saving of 50% on the number of gates required in implementation can be achieved.","PeriodicalId":148511,"journal":{"name":"International Conference on Pattern Recognition, Informatics and Medical Engineering (PRIME-2012)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121945596","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}

ECG signals change their statistical properties over time. Wavelet transform is the most powerful tool for analyzing the non-stationary signals. This paper shows that how it is useful in denoising non-stationary signals e.g. The ECG signals. We considered two types of ECG signal, without additional noise and corrupted by powerline interference and we realized the signal's denoising using wavelet filtering. The ECG data is taken from standard MIT-BIH Arrhythmia database, while noise signal is generated and added to the original signal using instructions in MATLAB environment. In this paper, we present Daubechies wavelet analysis method with a decomposition tree of level 5 for analysis of noisy ECG signals. The implementation includes the procedures of signal decomposition and reconstruction with hard and soft thresholding. Furthermore quantitative study of result evaluation has been done based on Signal to Noise Ratio (SNR). The results show that, on contrast with traditional methods wavelet method can achieve optimal denoising of ECG signal.","PeriodicalId":148511,"journal":{"name":"International Conference on Pattern Recognition, Informatics and Medical Engineering (PRIME-2012)","volume":"93 Pt A 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115786461","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}
