Patrick Klie studied Mathematics and Computer Science with Image Processing as field of application at the University of Hannover. He received his Dipl.-Math. degree from the University of Hannover in 2004. In 2000, he was awarded a prize by the Christian-Kuhlemann-Stiftung for best prediploma. His Studienarbeit (Thesis) was dealing with 'Compression of Compact Triangulated Manifolds without Border using Approximative Voronoi Diagrams'. The Fachbereich für Informatik of the University of Hannover awarded him a prize for best diploma thesis in the field of computer science in December 2004. He wrote his diploma thesis about 'Wavelet Decomposition of Scalar Functions on Surfaces', where he generalized Wim Sweldens' Lifting Scheme to apply wavelet transforms to functions defined on irregular discretizations in arbitrary dimensions. Since 2005 he has been working toward a PhD degree at the Institut für Informationsverarbeitung (formerly Institut für Theoretische Nachrichtentechnik und Informationsverarbeitung). His current research interests are multiple view geometry, 3D modeling, digital geometry processing, computational geometry and chromakeying/video matting.
