By bringing the symmetry plane of two rigid objects into coincidence, we can potentially match two objects approximately if there is no apparent elastic distortion. We illustrated this concept using Visible Human dataset, that included color cryosection, and radiological data, from which we extracted 3D mesh models of skin, brain and skull, and aligned them into nested bodies. Each model was generated with different spatial orientation and resolution, and their alignment, was guided by the underlying anatomical relationships in the head region, and a requirement, by an application that the meshes didn 't intersect. After alignment of the symmetry planes, obtained for each mesh using spatial affine transformations, the further geometric adjustment, to achieve complete registration of the nested models, is confined within a 2D plane (i.e. the symmetry plane). This simple method of registration of mesh anatomical models, has a potential to significantly reduce the degrees of freedom in various 3D brain registration applications. It can be also treated as a pre-registration operation before applying other registration methods.","PeriodicalId":299267,"journal":{"name":"2007 IEEE International Symposium on Signal Processing and Information Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123354001","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 proposed scheme is based on convolutional coding, where each codeword of the source node is partitioned into two parts. The first part is transmitted from the source to the relays and destination. The second part is transmitted simultaneously from the source and relay nodes to the destination. All the relay nodes are assumed to be operating in the decode-and-forward (DF) mode. At the destination, the two replicas of the second sub-codeword are combined using maximum ratio combining (MRC). The entire codeword is decoded via the Viterbi algorithm. We analyze the proposed scheme for L-relay channels in terms of its probability of symbol error and outage probability. In that, explicit upper bounds are obtained assuming M-ray phase shift keying (M-PSK) transmission. Our analytical results show that the maximum diversity order is achieved provided that the source-relay link is more reliable than the other links. Otherwise, the diversity degrades. However, in both cases, it is shown that substantial performance improvements are possible to achieve over noncooperative coded systems. Several numerical and simulation results are presented to demonstrate the efficiency of the proposed scheme.","PeriodicalId":299267,"journal":{"name":"2007 IEEE International Symposium on Signal Processing and Information Technology","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122952158","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}
