However, for some years there has been an increasing trend to use computers for entering, editing and printing Braille documents using special purpose software and printers. This paper describes some work which has been undertaken to optically read the Braille information from old paper copies, and particularly those which have become ‘tired’ and difficult to copy, into the computer so that they can be electronically stored and reproduced. Of specific interest are the techniques of using twin shadows (stereoumbral), i.e. subtracting two pictures of the Braille under different illumination conditions, to overcome the problems of background texture by segmenting this unwanted noise from the important relief information. Initial results for single sided Braille have been found to be promising, and the extension of this approach into the recognition of double sided Braille is discussed.</p></div>","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"18 4","pages":"Pages 341-354"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0745-7138(05)80034-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71786170","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}

One answer for this demand is expensive supercomputers. Another attempt is the collection of computational power in a network. Connected workstations operate for parallel computation. Our approach for collecting unused resources in workstation clusters enables dynamic distribution of computational load over the network. Any computer individually distinguishes the amount of server resources sharing for others in the network. Our architecture is based on the client /server model —clients divide potentially hard problems into sub problems and forward them to different servers in the network. The usage of standardized remote procedure calls (rpc) as the basic mechanism for transmission of data between the workstations allows the extension of the concept for heterogeneous environments. This article gives a discussion of our implementation for Windows NT and presents the latest benchmarks with two special parallel applications.","PeriodicalId":100806,"journal":{"name":"Journal of Microcomputer Applications","volume":"101 1","pages":"193-201"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79336107","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}

Hypermedia and temporal –spatial relationships between document media nodes are embedded into the data structure to support flexible presentation of multimedia information. Windows and a specially designed<em>Document Tree Dialog</em>provide an environment for efficient and user-friendly information retrieval. Other system issues such as security and customization are also addressed in the design.
