In approaches used up to now for image enhancement, the bands are typically processed separately, and this results in considerable distortion. The amount of information in many bands are also not very efficiently used. The objective of this work is to utilize the amount of information available more effectively, remove such distortions and to improve the appearance of the images. To realize this goal, we developed two new algorithms using transform techniques.

There is strong evidence that apoptosis (programmed cell death) occurs subsequent to ischemia, but its role as a mediator of delayed cell death has not been examined quantitatively. In this computational study, evidence is presented suggesting that apoptosis can cause tissue damage in a delayed fashion, with a temporal profile similar to that reported in cases of progressive stroke. The results from this study indicate that tissue damage is bi-phasic. In the acute phase (1-3 hours post-ictus), damage in the ischemic focus occurs as a result of severe metabolic insufficiency (necrosis). After a substantial time delay, a second form of cell death becomes apparent - mediated by apoptosis. The combination of necrosis and apoptosis accounts for the final infarct volume occurring in this model of ischemic stroke","PeriodicalId":306045,"journal":{"name":"2005 ICSC Congress on Computational Intelligence Methods and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127537435","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}

Conversely, for time series that exhibit no significant structural breaks or variance changes, fuzzy models trained on raw data perform better than hybrid fuzzy-wavelet models.
