So research into the methods of enhancing the document images, before presenting them to OCR softwares, is of utmost importance. The objective is to demonstrate a method of generating a high resolution document image, given a low resolution image. We propose a new method for improving the spatial resolution of document images. Here, we have built a deep neural network based model that utilizes the traditional interpolation methods, takes the best features from them and reconstructs a high resolution image from these features. This is achieved using a convolutional neural network (CNN). The CNN learns a high resolution patch from a corresponding low resolution patch, as a weighted non-linear combination of the outputs of different interpolation techniques. We call our technique as nonlinear fusion of multiple interpolations (NFMI). The NFMI method ensures that the model learns only the best features that can be extracted from all the interpolation techniques combined together. The use of traditional interpolation methods makes sure that the NFMI technique is not computationally expensive. Results on test images show a relative improvement of 54% in word recognition accuracy by OCR over the best interpolation technique for doubling the spatial resolution and 33% for quadrupling the resolution.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275410","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}

In this work, we have designed and demonstrated the enhancement in power conversion efficiency of a thin film ITO-cSi hetero-junction photovoltaic cell using photonic crystal as a back reflector making it both cheaper and efficient. The cell structure is analyzed using numerical simulation based on SYNOPSYS RSOFT CAD tool. The structure comprises of an anti-reflection coating of indium tin oxide, a p-type silicon layer and a back surface field layer of p++ type silicon. A photonic crystal (germanium rods in silicon-di-oxide) is implemented at the bottom of the solar cell in order to make the optical path length of incident light longer and reflect back the desired portion of the incident spectrum back to the active region to enhance the absorption process. The projected conversion efficiency as computed by rigorous coupled wave algorithm through RSOFT CAD tool is 27.09% and fill factor of 88.2% at AM 1.5, which is very impressing. A comparison study has also been made to show the enhancement in power conversion efficiency with and without the photonic crystal as a back reflector.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131348102","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 structure has two gates, a main gate (MG) and a side gate (SG). The main gate controls channel conductivity of the transistor similar to the conventional MOSFET gate electrode while the side gate induces substrate doping electrically. In the proposed structure source region is doped conventionally whereas doping of the drain region is controlled electrically by varying voltage at the SG. A zero or negative voltage on the SG induces a p-type drain region underneath it. Further, doping level of the region can also be controlled by varying SG work function and its length. An optimum value for the SG work function is selected to provide the maximum ION/lOFF current ratio. We have observed reduced peak electrical on the drain-channel junction which improves various short channel effects in the proposed device. The 2D calibrated simulation reveals that the threshold voltage (VTH) roll-off, drain induced barrier lowering (DIBL), subthreshold slope (SS) and ION/IOFF ratio are significantly improved in comparison to the conventional SOI MOSFET. These effects are simulated along with their conventional device counterpart.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123418488","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 approach is based on the Kalman filter technique. The parameters of noise signals are estimated using the Kalman filter. The idea behind this approach is to denoise the EEG signals and to preserve the stationarity by considering different window sized EEG time series. The results are validated in different window sizes of 300 milliseconds, 1 minute, 2 minutes, and 3 minutes up to 4 minutes data in different EEG. The entropy of the original signal and the estimated signal is also calculated, which shows the content of the signal. The Mean Square Error (MSE) and Signal to Noise ratio (SNR) in different channels are calculated for different window size EEG data. From the obtained results, we observe that with an increase in window size data, the MSE decreases and SNR increases and the entropy of the estimated signal is almost same as that of the original signal. Depending on the requirement, the window size is chosen. The smaller window gives better visibility, and the larger window gives less error. Estimation of noise quantifies the different types of inband artifacts contaminated the EEG signal.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126508019","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}
