Many theoretical works as well as numerous extensions have been studied rough out the years.\u0026nbsp; This talk will focus on variational approaches for multi-phase segmentation. For the first model, we propose a model built upon the phase transition model of Modica and Mortola in material sciences and a properly synchronized fitting term that complements it. For the second model, we propose a variational functional for an unsupervised multiphase segmentation, by adding scale information of each phase. This model is able to deal with the instability issue associated with choosing the number of phases for multiphase segmentation. Finally, I will discuss some new results of scale segmentation which is an extension from the unsupervised model.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022http:\/\/people.math.gatech.edu\/~kang\/\u0022 target=\u0022_blank\u0022\u003Ehttp:\/\/people.math.gatech.edu\/~kang\/\u003C\/a\u003E\u003C\/p\u003E\u003Cp\u003EYou are cordially invited to attend a reception in the lounge next to Klaus 1324 before the seminar to chat informally with faculty and students.
