The main complication is pulmonary embolism (PE) which is the third cause of vascular death after myocardial infarction and cardiovascular event. DVT onset is multifactorial (immobilization, surgery, age, cancers, genetic variations) and it is mostly diagnosed via ultrasound. In our project, we are interested in a new approach, which consists in using ultrasound and elastography to assess the mechanical properties of blood clots and to identify the thrombosis triggering factors. This means characterizing its structure, establishing his age, the cause of its formation and the risk of PE. In this paper, we aim to analyze the clot texture using the scattering operator which combines wavelet transform convolutions with non-linear modulus and averaging operators. The scattering operator is showing promising results in signal processing and especially in image classification. Therefore, we will apply this operator to our database and discuss the results of our simulation at the end of this manuscript.","PeriodicalId":407314,"journal":{"name":"2016 2nd International Conference on Frontiers of Signal Processing (ICFSP)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127427591","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}

Its progression to a pulmonary embolism can lead to significant mortality. DVT is a frequent, severe and often under-recognized diagnosis for critically ill patient. Many factors can increase the risk of DVT: immobilization, cancer, age, surgery, previous DVT, hormone, thrombophilia, etc. Ultrasonography is mostly performed for its diagnosis because it is easy, immediate and non-invasive. In our project, the main goal is to determine the possible correlations between the blood clot structure and the DVT triggering factors. To characterize its structure, we decided to combine ultrasound and elastography imaging. The latter technique is already used to diagnose other diseases such as liver fibrosis and gives promising results to date animal blood clot. This paper explains how we create our database using Toshiba's system. Our data are screenshot images that have to be prepared for further processing such as texture characterization.","PeriodicalId":407314,"journal":{"name":"2016 2nd International Conference on Frontiers of Signal Processing (ICFSP)","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122471668","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 implementation comprises of using various mathematical operations along side a pin-acceptance program in a multi-threaded environment. These threads are inserted randomly on each execution of the program to create confusion for the attacker. Moreover, the research proposes a more improved version of the pin-acceptance program by segmenting the pro-gram. The conventional approach is to check each character one at a time. This research takes the verifying process and separates each character check into its individual thread. Furthermore, the order of each verified thread is randomised. This further assists in the obfuscation of the process where the system checks for a correct character. Finally, the research demonstrates it is able to be more secure than the conventional countermeasures of random time delays and insertion of dummy code.","PeriodicalId":407314,"journal":{"name":"2016 2nd International Conference on Frontiers of Signal Processing (ICFSP)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126726122","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}

Various IMU-based and vision-based methods have been developed for measuring joint angles during walking process. Dynamic Vision Sensor (DVS) is a neuromorphic engineering product which outputs sequences of events describing the level of brightness change at the pixel level in an asynchronized manner, instead of discrete frames at a predefined frame rate. Due to its microsecond level resolution, DVS is regarded possessing a huge potential to dramatically increase the speed of sensing pipeline for various applications which traditional CMOS camera cannot fulfill. Hence, in this paper we introduce a novel system for gait analysis application; DVS and special markers are used to detect the ankle joint during walking and a method is developed to calculate the desired angle. Further, the robust locally weighted regression is employed as signal smoothing method to reduce the amount of noise. In order to evaluation its performance, an Inertial Measurement Unit (IMU)-based sensory system is also examined and compared in the same experiment and goniometer is used for providing the ground truth. By comparing the captured ankle joint angle trajectories using Dynamic Time Warping (DTW), DVS-based system appears to have higher accuracy in terms of ankle joint angle detection than IMU-based system.","PeriodicalId":407314,"journal":{"name":"2016 2nd International Conference on Frontiers of Signal Processing (ICFSP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128775014","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 most important symptoms of a disease include lesions, overdevelopment or underdevelopment of various parts of a plant, necrosis and deteriorated appearance. The color, area and the number of the lesions can often be used to determine the disease that has mortified a plant. A Windows Phone application capable of measuring the plant lesion features is described in this paper with an accuracy of approximately 90%. A reliable diagnosis can be performed by the measurement of the lesion features along with descriptive information provided by the user. Appropriate actions can be suggested to the user based on these measurements and the conclusions that the system can reach.","PeriodicalId":407314,"journal":{"name":"2016 2nd International Conference on Frontiers of Signal Processing (ICFSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131193866","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}
