Since the sample has a short biological life cycle; moreover, it is prone to alterations by inappropriate handling. One solution to this problem is the digitalization and virtualizations of slides. The group of Development and Technological Innovation-DIT- of BIOSYS LTDA Company is developing a technique. This consists of slide digitization under a microscope (several shots of images of cell fields) and subsequent virtualization, while the user (Bacteriologist or technologist, etc.) performs their daily work. Due to blurring (caused by slide movement) at moment of reading the slide, not all pictures can be used for slide virtualization. For this reason, we must choose the image of each cell field, with less blur. This work presents the results of the implementation of a direct method based on the application of the Haar Wavelet Transform, to detect and eliminate blurred images which are not necessary in the creation of a virtual slide. The results were obtained from a database with 20 sets of cell fields, which for each field were available 15 images with different focus conditions.","PeriodicalId":383297,"journal":{"name":"2012 XVII Symposium of Image, Signal Processing, and Artificial Vision (STSIVA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133298512","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}

Despite the different existing approaches that seek to address this problem, it is still possible to improve classification rates because during the stage of preprocessing of the signals from microelectrodes (which capture the neuronal activity of the brain), usually filtering a known signal portion: background neuronal activity. This preprocessing is done under the assumption that this part of the signal is not relevant for the classification process. However, in no event processing is performed to validate this assumption. This paper develops a methodology for the detection of determinism in background neuronal activity in the microelectrode recording signals (MER): application to Parkinson's disease. The proposal is based on the method of surrogate data, nonlinear tool has now been widely used for time series analysis, especially in physiological series.","PeriodicalId":383297,"journal":{"name":"2012 XVII Symposium of Image, Signal Processing, and Artificial Vision (STSIVA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129689177","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}
