However, the spatial, spectral, and temporal resolution of the imagery are imposing various limits. Lately, with the rise of the internet and smart mobile devices, social media with location-based information has been rapidly emerging. These circumstances led to the prevailing of new scenarios where fine-grained details of social bookmarking websites are enhanced with the wide coverage of satellites. Social media and satellites are both valuable sources of data. An event-driven data, designating either normal common events or unusual suspicious ones that may threaten human lives or damage the infrastructure. In this paper, we provide an insight into the present state of knowledge to better address the task of local suspicious event detection and linking social media with satellite imagery. Also, to track suspicious local events, we treated the detection problem as a retrospective problem by training different classifiers on the crisisLexT26 dataset. Furthermore, we introduced how to use the available geo-locations in the dataset to construct a geo-social dataset by linking it with remote sensing and retrieving satellite imagery before and after the event occurrence.","PeriodicalId":145369,"journal":{"name":"International Conference on Advanced Technologies for Signal and Image Processing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122914646","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}

This step is crucial, especially in Cardiac Magnetic Resonance Imaging (CMRI), as it allows to estimate important parameters for the quantification of cardiac contractile function such as cardiac volumes allowing calculation of the Ejection Fraction (EF) and myocardial thickening. The aim of this paper is to optimize and adapt the standard U-net architecture to our 2D cardiac Cine-MRI database in order to perform LV contours extraction automatically. The proposed method has been validated and tested on 70 patients with various cardiac pathologies. The obtained results show a great concordance between the ground truth and predicted segmentation with a mean Dice Similarity Coefficient (DSC) and Hausdorff Distance (HD) which reach 97.22% and 6.192 mm respectively at the end diastolic phase. These metric coefficients reach 93.5% and 8.679 mm respectively at the end systolic phase. The comparison results prove that the adopted method is likely to be considered as an effective tool for fully automatic LV segmentation.","PeriodicalId":145369,"journal":{"name":"International Conference on Advanced Technologies for Signal and Image Processing","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114888141","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}
