Seam carving method is an effective image retargeting method which suffers from high computational complexity. It requires one to find one-pixel wide minimum energy path in either vertical or horizontal direction, called seam, to reduce the image size by one pixel. In this paper, we propose an acceleration of the seam carving method by expanding the width of the seam making it multiple-pixel wide seam carving. The two types of energies: one corresponding to the pixels to be removed and another corresponding to the pixels across the multiple-pixel wide seam, increase as the width of the seam increases. In order to prevent the increase in these energies, we make the width of the seam adaptive as a function of the number of iterations. We find the width of a seam for each iteration as a prior for the seam carving process using a set of maximum energy seams in an orthogonal direction to the seam carving process. Qualitative and quantitative results prove that the proposed method performs faster and better than the other state-of-the-art image retargeting operators.","PeriodicalId":6870,"journal":{"name":"2019 National Conference on Communications (NCC)","volume":"14 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82918757","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 is a growing interest among researchers for automatic detection of MI using computer algorithms. Based on the spatial location of damaged tissues MI is further categorized as anterior MI, septal MI, lateral MI, inferior MI and posterior MI. Among all, automatic detection of posterior MI (PMI) with standard 12-lead electrocardiogram (12-lead ECG) signal is challenging as it does not have monitoring electrodes posterior to human body. In this paper, we propose an automatic method for PMI detection using 3-lead vectorcardiogram (3-lead VCG) signal. The proposed approach exploits changes in electrical conduction properties of heart tissues during cardiac activity for healthy control (HC) and PMI subjects in three-dimensional (3D) space. To quantify these changes multiscale eigen features (MSEF) of subband matrices are used. Furthermore, we propose a cost sensitive weighted support vector machine (WSVM) classifier to combat class imbalance, which is a common problem in real-world disease data classification. The publicly available PhysioNet/PTBDB diagnostic database has been used to validate the proposed method by using a total of 1463 HC, and 148 PMI 4 sec 3-lead VCG signals. The best test accuracy of 96.69%, sensitivity of 80%, and geometric mean of 88.72% are achieved by WSVM classifier with radial basis function (RBF) kernel.","PeriodicalId":6870,"journal":{"name":"2019 National Conference on Communications (NCC)","volume":"16 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72662453","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 paper, design of discrete frequency-coding waveform (DFCW) using linear chirp (LC) pulse and pseudo-noise (PN) code sequence is proposed to improve the autocorrelation sidelobe peak (ASP) and cross-correlation peak (CCP) levels of the waveforms. To achieve minimum cross-correlation levels between different waveforms, for a multiuser and MIMO radar system, a two-stage optimization process is proposed. In the first stage, optimization of the frequency-firing sequence of the waveforms is performed and in the second stage, PN-code sequence optimization is performed in order to obtain the overall optimized waveforms. The performance of the proposed waveforms in a multiuser and MIMO radar system is analyzed. In comparison with the performance of multiuser and MIMO radar system designed using other available DFCW, the performances of the radar systems using proposed waveforms are better in terms of maintaining lower ASP and CCP levels. In addition, performance of the proposed waveforms under Doppler frequency variation is also presented.","PeriodicalId":6870,"journal":{"name":"2019 National Conference on Communications (NCC)","volume":"355 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76492539","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}
