The algorithm is based on a threshold detector using the smoothed optical flow value. The optical flow is calculated from the video frames of long-term video-EEG monitoring. We conducted a computational experiment that showed the following: (a) artifacts are detected with accuracy acceptable for diagnosing cerebral ischemia during synchronous analysis of video data and EEG signals; (b) artifacts can be detected in real time.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131089063","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 proposed methods and means of ECS processing refer to the 4th generation electrocardiography, which allows obtaining new information about cardiac processes more reliably and revealing clinically significant cardiac pathologies under screening conditions.An approach to building NESS has been proposed that consists in \"convergence\" of solutions of direct and inverse electrocardiology problems with subsequent visualization of the results of the solutions for a visual presentation of the heart electrical activity (HEA) to the physician. Increased efficiency of NESS is due to the original \"technological pipeline\" of ECS processing: registration of multiple ECS leads, pre-processing of ECS, multivariate analysis of ECS, modeling and visualization of ECS.Physicians are provided with a tool for screening and diagnostics of HEA, providing increase of efficiency of HEA assessment on the basis of collection, processing and transfer of cardiographic information; modeling of HEA; visualization of HEA analysis results.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133300257","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 method may be promising for assessing pathological changes in clinical practice.

In case of a complex image of the resulting logarithmic curve, a piecewise linear approximation is proposed for calculating the generalized value of the Hurst exponent. The analysis of self-similar properties in separate sections of the time evolution of living systems is performed using the localization procedure. The capabilities of the proposed algorithms were demonstrated by analyzing the scaling features of the time dynamics of the tremor velocity in Parkinson's disease, the bioelectrical activity of the brain of patients with epilepsy.
