Statistics show that 20% of the 9/11 victims, identified in the first year, were manually identified using dental records. Moreover, 75% of Tsunami victims in Thailand were similarly identified using dental records, compared to 0.5% identified using DNA. This paper addresses the first important problem of an Automated Dental Identification System (ADIS). This system matches image features extracted from multiple dental radiographic records. Dental radiograph record of an individual usually consists of radiographic films. It is an essential step to accurately segment these films from their constituent dental records in order to extract the dental features and achieve high level of automated postmortem identification. In this paper, we propose an automated approach to the problem of segmenting films from their dental records. Challenges include the variability in the background of the dental records including its gray intensity and texture, and variation in the number of films and their dimensions. Our three-stage approach is based on concepts of thresholding, connectivity, and mathematical morphology. We show by experimental evidence that our approach achieves 92% accuracy compared to 74% using previous work suggested in the literature.","PeriodicalId":389538,"journal":{"name":"2008 Biometrics Symposium","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125763616","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 problem has been recently faced by template update techniques. The majority of the proposed techniques can be regarded as ldquoself-updaterdquo methods, as the system updates its own templates using the recognition results provided by the same templates. However, this approach can only exploit the input data ldquonearrdquo to the current templates resulting in ldquolocalrdquo template optimization, namely, only input samples very similar to the current templates are exploited for update. To address this issue, this paper proposes a ldquoglobalrdquo optimization of templates based on the graph mincut algorithm. The proposed approach can update templates by analysing the underlying structure of input data collected during the systempsilas operation. This is achieved by a graph drawn using a pair-wise similarity measure between enrolled and input data. Investigation of this novel template update technique has been done by its application to face verification, as a case study. The reported results show the effectiveness of the proposed technique in comparison to state of art self-update techniques.","PeriodicalId":389538,"journal":{"name":"2008 Biometrics Symposium","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114313724","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}
