Present cardiovascular function assessment techniques encompass a broad range of diagnostic tools which in most cases involve high and mid level cost instrumentation. They include among others instrumentation as a part of nuclear cardiology, cardiac catheterization, cardiac ultrasound, relatively basic multiple or simple channel ECG acquisition systems, and other. These techniques and related instrumentation represent very useful and powerful tools to diagnose and/or manage particular cardiac abnormalities; however they are not suitable for broader population low cost basic supplemental cardiac screening. Therefore, these studies focused on a structured assessment of cardiac sound traits as related auscultation is a part of standard medical exams and globally accepted procedures. For these reasons a dedicated cardiac sounds assessment algorithm was developed and has been tested on heart sound database that contains 565 signals encompassing 202 normal and 363 abnormal sounds. A broad range of diverse cardiac sound indicators, versatility of database, and derived characteristics validate potency of possible clinical usefulness and potential for a low cost broader diagnostic screening. In particular, the group of abnormal heart sounds contains samples of 35 different heart abnormalities which are divided into two groups including Group I that contains 28 different heart abnormalities that are 81.81% successfully detectable by the developed algorithm and Group II that contains 7 different heart abnormalities that do not exhibit the frequency change of S1 sound and are not classified by the proposed method. Normal heart sounds in 97.03% of cases were successfully classified with the developed method which is addressing the needs for a selected cardiac screening in light of increasing prevalence of cardiovascular diseases.","PeriodicalId":196438,"journal":{"name":"2014 Pan American Health Care Exchanges (PAHCE)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114829972","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 particular, skin wrinkles typically occur due to aging processes, including loss of body mass, sun damage, smoking, squinting and other factors. They represent a clear and easily accessible indicator of changes. As such, one can also acquire useful information about the aging process in skin by analyzing the wrinkles. To this end, we utilize a combination of numerical techniques, including color quantization, image segmentation, and various edge detection algorithms in order to perform automated wrinkle counting and wrinkle density calculations. As a more appropriate alternative to chronological age, such a methodology allows us to come up with quantifiable measures for skin aging, which may be used for performing statistics and extracting general patterns associated with physiological aging of the skin, as well as extending such numerical techniques for other biomedical applications in which distinct topological features contain important information about biological processes. Different subjects were used to test the techniques and extract aging patterns by examining the skin immediately underneath the lower eyelid as our region of interest. Numerically processed photographs, included counting the number of wrinkles meeting predefined threshold conditions, and calculating the corresponding wrinkle density for a given subject and particular conditions. Applicability and practicality of different edge detection methods were also a part of the studies as demonstrated.","PeriodicalId":196438,"journal":{"name":"2014 Pan American Health Care Exchanges (PAHCE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125384130","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}
