/_Abstract:_///

/Image segmentation separates the image into different regions to 
simplify the image and identify the objects easily. Image segmentation 
has been extensively studied, and Mumford-Shah and Chan-Vese model are 
one of the most well-known variational model in the field. This talk 
will focus on the multiphase aspect of such problem, in particular 
unsupervised model and its extensions to various applications. The 
connection to data clustering will be considered, scale segmentation and 
application to 3D flash Lidar image will presented. This talk will also 
include a model segmenting piecewise constant images with irregular 
object boundaries./
