After emphasizing the digitized mammograph images by Laplacian operation, a threshold processing was applied to extract the microcalcifications. Although microcalcification opacity exists for both malignant and benign cases, there were differences in the distribution and the numbers of opaque points. To give a quantitative expression for the microcalcification, the data were evaluated by using fractal dimension. As a result of processing 25 cases, including 10 benign cases, up to 14 out of 15 malignant cases were able to be separated using the fractal dimension.<<ETX>>","PeriodicalId":223769,"journal":{"name":"[Proceedings] Singapore ICCS/ISITA `92","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123669871","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 hardware is less complex than that of an output queueing switch. The reduction in the hardware complexity can be obtained without either losing the self-routing property or suffering from performance degradation under uniform and nonuniform traffic. The switch is constructed with shift network. It has an internal buffer that is interconnected in the banyan networks. The shift networks allow a cell to be sent to the correct output port. It needs only the destination address to route a cell regardless of the state of the switch. Although the switch becomes blocking, it retains the self-routing property and achieves the maximum throughput of 100% with only small additional delay.<<ETX>>","PeriodicalId":223769,"journal":{"name":"[Proceedings] Singapore ICCS/ISITA `92","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130143427","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}
