Our research addresses three steps in this process. First is identifying lung airways in radiological images. Our approach is based on a combination of geometric analysis of gradient vector flow and graph-based  algorithms. Second is a novel method for robust and efficient computation of medial curves for complex biomedical geometries. This algorithm is based on three key concepts: a local orthogonal decomposition of geometry into substructures, a differential concept called the interior center of curvature, and integrated stability and consistency tests. Finally, we introduce variational method for generating prismatic boundary-layer meshes. Compared to existing methods, our approach is novel in the following aspects: it relies on feature size to make resulting mesh scale invariant and prevent global self-intersections; it uses face-offsetting method to propagate surface mesh to generate the high-quality prismatic layers; finally, it allows to add prismatic boundary layer to any  tetrahedral mesh while preserving structural qualities of original discretization."},{"label":"dcterms.available","value":"2013-05-22T17:34:29Z"},{"label":"dcterms.contributor","value":"Einstein, Daniel."},{"label":"dcterms.creator","value":"Dyedov, Volodymyr"},{"label":"dcterms.dateAccepted","value":"2013-05-22T17:34:29Z"},{"label":"dcterms.dateSubmitted","value":"2015-04-24T14:46:31Z"},{"label":"dcterms.description","value":"Department of Applied Mathematics and Statistics"},{"label":"dcterms.extent","value":"114 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/59639"},{"label":"dcterms.issued","value":"2012-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2013-05-22T17:34:29Z (GMT).
