Ophthalmologist describes a vision anomaly as any kind of vision loss, be it partial or total vision loss. The cause of vision loss can be traced back to genetic conditions, improper lifestyle, medical conditions and accidental causes. Visually evoked potentials (VEP) are often used in cases where the medical experts might have difficulties in determining the cause of the problem. VEP has often been reported in the literature as a reliable method for detecting visual abnormalities. By analyzing the recorded brain responses toward a visual stimulus, it is possible for the ophthalmologist to make an appropriate estimation. Since the analysis of VEP by the medical experts is still subjective, there is a need for a more comprehensive analysis method. Researchers are now trying to explore the spectral information of the VEP for easier diagnosis. In this regard, this work explores the use of Stockwell transform (ST) for the analysis of VEP signals. Via ST-based multi-resolution decomposition of the signals, the time-frequency information matrix (ST-matrix) is obtained. Statistical features extracted from ST-matrix were classified using least square support vector machine (LSSVM) and probabilistic neural network (PNN). The investigation results suggest that the LSSVM classifier was able to provide 96.07% of accurate prediction for selected visual anomaly investigated.","PeriodicalId":314829,"journal":{"name":"2016 IEEE 12th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123037303","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}

InSAR measurement derived from phase data is not only ambiguous by its modulo-2pi mathematical-ill pose, but also further corrupted by noise. Therefore, we suggest an adaptive least mean square (LMS) algorithm based on steepest descent method for noise reduction purpose. Besides, a scheme which incorporates such filter into a Itoh two-dimensional phase-unwrapping is proposed. The phase estimation procedures are implemented to reconstruct a simulated interferogram of terrain structure. For the quantitative assessment, we employ different types of quality metrics to measure the estimated outcome of InSAR terrain image which includes root mean square error (RMSE) and signal-to-noise ratio (SNR). The estimated outcomes are also reconstructed into three dimensional plotting for visual assessment. By refering to the similar scheme, other noise reduction filters include wieners filter and median filter are implemented for performance comparison. The simulated results show that the proposed method is able to filter noise without corrupted the useful phase information and achieves lowest error energy among other filters. Thus, it is a valuable technique for InSAR terrain phase estimation.","PeriodicalId":314829,"journal":{"name":"2016 IEEE 12th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123409462","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 aim of this study is to identify a hesitant step-up pattern that could be linked to an increasing risk of falling in the elderly. The methods used are autoregressive moving average (ARMA) (rate of changes or fluctuation) and the area of a curve under the slope of the Z-force signal (Z-Area) during stepping up. Dynamic balance is evaluated using a force plate for 10 control subjects, 10 elderly subjects and 10 rest home subjects under control (eyes open) conditions. Each subject is tested once per weekday for three weeks. Temporal and ground reaction force parameters are measured. Lower values of ARMA variance or rate of changes, and a higher value of Z-Area are indicative of a more hesitant step up. Control subjects have significantly higher values of ARMA than the rest-home dwelling elderly, thus providing a sensitive method for identifying the subtle changes in z-force signals associated with a hesitant step-up. Similarly, elderly subjects have significantly greater Z-Area values than the control subjects. The ARMA and Z-Area parameters enable the detection of a hesitant step-up that could be related to an increasing risk of falling.","PeriodicalId":314829,"journal":{"name":"2016 IEEE 12th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116934761","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}
