Jung-Ha An (IMA): A Variational PDE Based Level Set Method for a Simultaneous
Segmentation and Non-Rigid Registration
A new variational PDE based level set method for a simultaneous
image segmentation and non-rigid registration using prior shape
and intensity information is presented. The segmentation is
obtained by finding a non-rigid registration to the prior shape.
The non-rigid registration consists of both a global rigid
transformation and a local non-rigid deformation. In this model, a
prior shape is used as an initial contour which leads to decrease
the numerical calculation time. The model is tested against two
chamber end systolic ultrasound images from thirteen human
patients. The experimental results provide preliminary evidence of
the effectiveness of the model in detecting the boundaries of the
incompletely resolved objects which were plagued by noise,
dropout, and artifact.
