The tumor region can be detected by segmentation of brain Magnetic Resonance Image (MRI). In the case of suspected brain tumor, the location and size of tumor can be determined with the help of radiologic evaluations. The report of this evaluation is very important for futher diagnosis and treatment planning. The detection of tumor must be fast and accurate for the diagnosis purpose. The segmentation or extraction of brain tumor from MRI is possible manually. But it is time consuming and tedious. Also the accuracy depends upon the experience of expert. Hence, the computer aided automatic segmentation has become important. MRI scanned images offer valuable information regarding brain tissues. MRI scans provide very detailed diagnostic pictures of most of the important organs and tissues in our body. It is generally painless and noninvasive. It does not produce ionizing radiation. So MRI is one of the best clinical imaging modalities. Several automated segmentation algorithms have been proposed. But still segmentation of MRI brain image remains as a challenging problem due to its complexity and there is no standard algorithm that can produce satisfactory results. The aim of this research work is to propose and implement an efficient system for tumor detection and classification. The different steps involved in this work are image preprocessing for noise removal, feature extraction, segmentation and classification. Proposed work preprocessed the MRI brain image using anisotropic diffusion filters. In the feature extraction step, discrete wavelet transforms(DWT) based features are extracted. The extracted features was given as input to the segmentation stage. Here Support Vector Machine (SVM) was used for tumor segmentation and classification.","PeriodicalId":123773,"journal":{"name":"2017 International Conference on Signal Processing and Communication (ICSPC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121823201","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}

Sparse vectors for these images are obtained using learned dictionaries. The sparse coefficients are fused and with fused coefficients the enhanced higher resolution image is retrieved back.

The use of satellite images is more prevalent nowadays in many real time surveillance applications and it leads to the need of simple and accurate processing. The advent of machine learning classifiers improved the efficiency of satellite image applications. However, the ground truth data availability and spatial data labeling are certain serious limitations for supervised satellite image classification. Thus change monitoring models are highly dependent on unsupervised clustering methods with the compromised level of accuracy. This paper is focused on addressing the steps to overcome the above said ground truth validation, labeling and other feature discrimination issues in a supervised soft classifier model for simple change recognition of seasonal water bodies in satellite images.","PeriodicalId":123773,"journal":{"name":"2017 International Conference on Signal Processing and Communication (ICSPC)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131761486","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}

WVSNs provides better results when it come to object detection since it consists of several tiny camera sensors which can capture the object's image and helps in identifying the object more precisely. There are some limitations of WVSN like battery constraints, limited storage memory so to overcome these limitations the proposed method is using block based compressive sensing technique (BCS) which applies compression only to the required blocks of image rather than applying it on whole image frame. The proposed method also incorporates a change detecting algorithm which will work only if the Mean square error (MSE) comparator crosses its predefined threshold value. The main aim of the proposed method is to achieve faster reconstruction of image with acceptable image quality so, to attain the required performance contourlet transform and projection driven compressive sensing recovery technique has been used. Also to increase the speed of reconstruction wiener filter is incorporated into iterative projected landweber compressive sensing recovery technique. The results have shown that the proposed block based compressive sensing with smooth projected landweber performs better than other methods as compared to quality of the reconstructed image.","PeriodicalId":123773,"journal":{"name":"2017 International Conference on Signal Processing and Communication (ICSPC)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134174383","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}

Secure user authentication is one of the main necessities of cloud computing in order to avoid loss for a cloud service provider and to provide secure service to the valid user. A secure biometric based authentication scheme is proposed which provides secure user identification, mutual authentication, session key issue and proxy issue in cases where a single cloud service provider (SP) provides more than one service.

Poor PQ may lead to partial or complete failure of equipment, loss of important data etc. The mitigation strategy can also be planned only if these PQ disturbances are correctly monitored. Conventional way of identifying PQ disturbances using Fourier Transform produces unrealistic results in case of non-stationary PQ disturbances. So, in order to measure it accurately, Wavelet packet transform is explored with its capability. In this paper, an attempt has been made to analyse PQ disturbances using M-band Wavelet packet transform. For Power quality disturbances such as voltage sag, voltage swell, momentary interruptions, voltage sag plus harmonics, voltage swell plus harmonics and flicker a statistical parameter RMS is computed for each WPT coefficient. Analysis is done for different magnitudes and time durations of PQ disturbances which are simulated as per their IEEE 1159-2009 standards definition.","PeriodicalId":123773,"journal":{"name":"2017 International Conference on Signal Processing and Communication (ICSPC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134623374","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}

Data transmission in WSNs is not an easy task due to resource constrained nodes, limited battery time, low transmission power, etc. energy is the crucial parameter in WSNs for sensing and transmitting the sensed data to the sink. WSNs are deployed in hostile and remote locations making them vulnerable to various types of security attacks. Thus design of WSNs routing protocols must consider various routing challenges and design issues. The survey describes various data collection approaches and efficient routing protocols to reduce the networks energy consumption. The paper presents various routing challenges as well as the limitations of WSNs.
