The image processing environment which is Windows based, encapsulates a multiple-document interface (MDI) and is menu driven. Object (shape) parameter extraction is focused on features that are invariant in terms of translation, rotation and scale transformations. The neural network models incorporated into the environment allow both clustering and classification of objects from the analysed image. Mapping neural networks perform input sensitivity analysis on the extracted feature measurements and thus facilitates the removal of irrelevant features and improvements in the degree of generalisation.","PeriodicalId":292377,"journal":{"name":"Proceedings of Computer Based Medical Systems","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129038614","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}

To attain this ability, in many cases customer-tailored user interfaces plus a long training process is necessary. Even learning the relation between reason and effect and experiencing self effectiveness (being able to make something happen in the environment) is the first big challenge and often an entire new experience. Hence, a technical system able to meet the needs of these users has to fulfill three criteria: (1) give optimal support to the training process; (2) support the facilitators with a tool to easily adapt the system to the rapidly changing user needs; (3) be able to grow from the first experience of self effectiveness up to a multi functional, multi purpose technical aid. The paper discusses an innovative technical assistance system developed at the Vienna University of Technology which is especially for multiple impairments and the training process. The authors look back on one and a half years of practical evaluation of the technical assistance system in a support center for motor and multiple impaired persons. After introducing the concept of the technical assistance system and pointing out its special features, two case studies illustrate the practical application of the system.","PeriodicalId":292377,"journal":{"name":"Proceedings of Computer Based Medical Systems","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132504078","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 amount of such information is enormous and is still growing with the introduction of new equipment. The problem is the choice of the exact details of interest from this huge amount of information, how to make it more visible, and how to store it etc. in order to enable the physician to make better and quicker decisions about exact diagnosis and localization of the pathology for further medical interventions. In such cases computer based intelligent support can help a physician to acquire more important information from X-ray images. This is very important for drawing proper conclusions and taking appropriate action. The authors are developing a prototype of a computer based intelligent support for neuroimaging (CBISN). Some practical examples are presented.","PeriodicalId":292377,"journal":{"name":"Proceedings of Computer Based Medical Systems","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127534718","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 means that records from different operations are of different lengths since the amount of data collected depends on the length of the operation. Padding all records to the same length is a waste of disk space and processing time. In general statistical software packages require constant length records and much of the data is redundant and will not be used in the analysis. This paper discusses a method using a statistics package to format the operation records into one file.","PeriodicalId":292377,"journal":{"name":"Proceedings of Computer Based Medical Systems","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129820188","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 authors argue in favor of using the raw data from such force platforms and apply artificial neural networks for gait malfunction identification.

The employed classification approach is learning vector quantization which proved to be highly robust in the training process yielding a remarkably high recognition accuracy of gait patterns.","PeriodicalId":292377,"journal":{"name":"Proceedings of Computer Based Medical Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123973482","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}
