This paper compares the performance between two popular statistical signal processing tools, viz., principal component analysis (PCA) with fast independent component analysis (/ICA) in reduction of MA from finger pulse signal collected from 30 human volunteers. A multivariate dataset was generated with systolic peak-aligned Photoplethysmogram (PPG) beats extracted from time series data. After eigenvalues decomposition of the covariance matrix, the original data was reconstructed using the first principal component. The mean correlation coefficient of average beat template of ICA preprocessed data and clean data, averaged over 30 volunteers is 0.9876 while that of PCA preprocessed data with clean data is 0.9778. With white Gaussian noise of known SNR, maximum absolute error for PCA preprocessed data is very small, 3.14% from SNR 25dB onwards. It was also found that beat to beat correlation is higher in the PCA preprocessed data.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"53 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114037609","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}

Accurate deployment of sensor nodes and Base Station (BS) is one of the obligatory factors for efficient wireless communication in WSN. This paper proposes a Java® based desktop application tool for simulating and visualizing the behavior of the sensor network concurrently. This tool allows user to personalize various system parameters like number of sensor nodes, area of deployment, nature of node placement, positioning of base station, etc. by their own choice. This simulator is embedded with some Energy Efficient Routing Algorithms (EERAs) for enhancement of its effectiveness. Users can examine their own networks using EERA and judge its effectiveness. This tool has been designed for general purpose applications where all parameters are customizable and independent of application. Users can bias the simulator in an uncomplicated way prior to the starting of the simulation in accordance to the application demand. Visualization of data-link, high customizability and short initial setup time are the key features of this application.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127337569","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}

An image is blurred due to motion between the camera or sensor and the object, defocusing of the lens, atmospheric turbulence, etc. Images can be restored if information about the original image or the blur is known. Degradation due defocus blur is considered in this paper. The estimation of defocus blur radius is treated as a classification problem here. A technique to classify the blur radius using random forest classifier is proposed in this paper. Third and fourth statistical moments, calculated on the spectrum of the blurred image are used as features for classification in the proposed method. The proposed technique is applied on images from the USC-SIPI Image database. The experiment results display defocus radius classification accuracy of 94.37%. The selection of skewness and kurtosis as handcrafted features for the defocused blur image and usage of random forest classifier for defocus radius classification has been approached for the first time in such problem. The choice of features adds to the novelty and efficiency of this approach.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129557701","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}

A wall shaped raised ground structure (RGS) is used around the stacked rectangular microstrip patch to widen the beamwidth. A material with very low dielectric constant is used to fill the space left between RGS and two layers of rectangular microstrip patch. Low dielectric constant makes the antenna less dependent on the finite size of ground plane or the host structure due to the absence of higher order modes of surface waves and retains the purity of broad radiation beam. In order to separate radiating patch from its feeding structure and for circular polarization (CP), a crossed slot aperture coupled technique is used. A nozzle shaped conformal radome is used to protect antenna from the environmental hazards and to reduce aerodynamic drag as well. It is observed that antenna provides excellent electrical and radiation characteristics. 10-dB Return loss bandwidth of 30%, 3-dB axial ratio (AR) bandwidth of 15%, realized gain of 6.2 dBiC, 3-dB beamwidth of 110° × 110° and 3-dB axial ratio beamwidth of 170° × 175° at center frequency of 9.45 GHz of X-band are observed.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128392344","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}

There are different types of techniques to give good quality of an image. Global image contrast enhancement is one of the most commonly used technique to enhance the quality of an image, but it has some disadvantages with the fact that it does not consider the local details of an image. Local details of an image are very important while analyzing an image, which is that of the scientific study of an image like the image taken from planetary bodies, satellite image and medical images. Local details of an image are very important for diagnosing a particular ailment. When either local contrast enhancement or global contrast enhancement is used alone, there is loss of brightness of the image. In order to address and reduce this discrepancy of individual enhancement methods, a new method is presented in this paper, that uses both local and global enhancement methods on the same image. First, the image is locally enhanced and the output is again processed by the global enhancement method thereby giving a properly enhanced image without losing the brightness of the image. This enhancement method is simulated in MATLAB and results are verified on the parameters of image quality.","PeriodicalId":383252,"journal":{"name":"2017 International Conference on Innovations in Electronics, Signal Processing and Communication (IESC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131758064","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}
