DESCRIPTION:Conformal (C) / Quasi-conformal (QC) geometry has
a long history in pure mathematics\, and is an act
ive field in both modern geometry and modern physi
cs. Recently\, with the rapid development of 3D di
gital scanning technology\, the demand for effecti
ve geometric processing and shape analysis is ever
increasing. Computational conformal / quasi-confo
rmal geometry plays an important role for these pu
rposes. Applications can be found in different are
as such as medical imaging\, computer visions and
computer graphics.\n\nIn this talk\, I will first
give an overview of how conformal geometry can be
applied in medical imaging and computer graphics.
Examples include brain registration and texture ma
pping\, where the mappings are constructed to be a
s conformal as possible to reduce geometric distor
tions. In reality\, most registrations and surface
mappings involve non-conformal distortions\, whic
h require more general theories to study. A direct
generalization of conformal mapping is quasiconfo
rmal mapping\, where the mapping is allowed to hav
e bounded conformality distortions. In the second
part of my talk\, theories of quasicoformal geomet
ry and its applications will be presented. In part
icular\, I will talk about how QC can be used for
registration of biological surfaces\, shape analys
is\, medical morphometry and the inpainting of sur
face diffeomorphism.\n\n
